+
+Status of this Memo
+
+   This document specifies an Internet standards track protocol for the
+   Internet community, and requests discussion and suggestions for
+   improvements.  Please refer to the current edition of the "Internet
+   Official Protocol Standards" (STD 1) for the standardization state
+   and status of this protocol.  Distribution of this memo is unlimited.
+
+Abstract
+
+   The Hypertext Markup Language (HTML) is a simple markup language used
+   to create hypertext documents that are platform independent. HTML
+   documents are SGML documents with generic semantics that are
+   appropriate for representing information from a wide range of
+   domains. HTML markup can represent hypertext news, mail,
+   documentation, and hypermedia; menus of options; database query
+   results; simple structured documents with in-lined graphics; and
+   hypertext views of existing bodies of information.
+
+   HTML has been in use by the World Wide Web (WWW) global information
+   initiative since 1990. This specification roughly corresponds to the
+   capabilities of HTML in common use prior to June 1994. HTML is an
+   application of ISO Standard 8879:1986 Information Processing Text and
+   Office Systems; Standard Generalized Markup Language (SGML).
+
+   The "text/html" Internet Media Type (RFC 1590) and MIME Content Type
+   (RFC 1521) is defined by this specification.

+   create hypertext documents that are portable from one platform to
+   another. HTML documents are SGML documents with generic semantics
+   that are appropriate for representing information from a wide range
+   of domains.

+RFC 1866            Hypertext Markup Language - 2.0        November 1995
+
+
+   As HTML is an application of SGML, this specification assumes a
+   working knowledge of [SGML].
+
+1.1. Scope
+
+   HTML has been in use by the World-Wide Web (WWW) global information
+   initiative since 1990. Previously, informal documentation on HTML has
+   been available from a number of sources on the Internet. This
+   specification brings together, clarifies, and formalizes a set of
+   features that roughly corresponds to the capabilities of HTML in
+   common use prior to June 1994. A number of new features to HTML are
+   being proposed and experimented in the Internet community.
+
+   This document thus defines a HTML 2.0 (to distinguish it from the
+   previous informal specifications). Future (generally upwardly
+   compatible) versions of HTML with new features will be released with
+   higher version numbers.
+
+   HTML is an application of ISO Standard 8879:1986, "Information
+   Processing Text and Office Systems; Standard Generalized Markup
+   Language" (SGML). The HTML Document Type Definition (DTD) is a formal
+   definition of the HTML syntax in terms of SGML.
+
+   This specification also defines HTML as an Internet Media
+   Type[IMEDIA] and MIME Content Type[MIME] called `text/html'. As such,
+   it defines the semantics of the HTML syntax and how that syntax
+   should be interpreted by user agents.
+
+1.2. Conformance
+
+   This specification governs the syntax of HTML documents and aspects
+   of the behavior of HTML user agents.
+
+1.2.1. Documents
+
+   A document is a conforming HTML document if:
+
+        * It is a conforming SGML document, and it conforms to the
+        HTML DTD (see 9.1, "HTML DTD").
+
+            NOTE - There are a number of syntactic idioms that
+            are not supported or are supported inconsistently in
+            some historical user agent implementations. These
+            idioms are identified in notes like this throughout
+            this specification.
+
+        * It conforms to the application conventions in this
+        specification. For example, the value of the HREF attribute
+
+

+
+RFC 1866            Hypertext Markup Language - 2.0        November 1995
+
+
+        of the <A> element must conform to the URI syntax.
+
+        * Its document character set includes [ISO-8859-1] and
+        agrees with [ISO-10646]; that is, each code position listed
+        in 13, "The HTML Coded Character Set" is included, and each
+        code position in the document character set is mapped to the
+        same character as [ISO-10646] designates for that code
+        position.
+
+            NOTE - The document character set is somewhat
+            independent of the character encoding scheme used to
+            represent a document. For example, the `ISO-2022-JP'
+            character encoding scheme can be used for HTML
+            documents, since its repertoire is a subset of the
+            [ISO-10646] repertoire. The critical distinction is
+            that numeric character references agree with
+            [ISO-10646] regardless of how the document is
+            encoded.
+
+1.2.2. Feature Test Entities
+
+   The HTML DTD defines a standard HTML document type and several
+   variations, by way of feature test entities. Feature test entities
+   are declarations in the HTML DTD that control the inclusion or
+   exclusion of portions of the DTD.
+
+    HTML.Recommended
+            Certain features of the language are necessary for
+            compatibility with widespread usage, but they may
+            compromise the structural integrity of a document. This
+            feature test entity selects a more prescriptive document
+            type definition that eliminates those features. It is
+            set to `IGNORE' by default.
+
+            For example, in order to preserve the structure of a
+            document, an editing user agent may translate HTML
+            documents to the recommended subset, or it may require
+            that the documents be in the recommended subset for
+            import.
+
+    HTML.Deprecated
+            Certain features of the language are necessary for
+            compatibility with earlier versions of the
+            specification, but they tend to be used and implemented
+            inconsistently, and their use is deprecated. This
+            feature test entity enables a document type definition
+            that allows these features. It is set to `INCLUDE' by
+            default.

+
+
+            Documents generated by translation software or editing
+            software should not contain deprecated idioms.
+
+1.2.3. User Agents
+
+   An HTML user agent conforms to this specification if:
+
+        * It parses the characters of an HTML document into data
+        characters and markup according to [SGML].
+
+            NOTE - In the interest of robustness and
+            extensibility, there are a number of widely deployed
+            conventions for handling non-conforming documents.
+            See 4.2.1, "Undeclared Markup Error Handling" for
+            details.
+
+        * It supports the `ISO-8859-1' character encoding scheme and
+        processes each character in the ISO Latin Alphabet No. 1 as
+        specified in 6.1, "The HTML Document Character Set".
+
+            NOTE - To support non-western writing systems, HTML
+            user agents are encouraged to support
+            `ISO-10646-UCS-2' or similar character encoding
+            schemes and as much of the character repertoire of
+            [ISO-10646] as is practical.
+
+        * It behaves identically for documents whose parsed token
+        sequences are identical.
+
+        For example, comments and the whitespace in tags disappear
+        during tokenization, and hence they do not influence the
+        behavior of conforming user agents.
+
+        * It allows the user to traverse (or at least attempt to
+        traverse, resources permitting) all hyperlinks from <A>
+        elements in an HTML document.
+
+   An HTML user agent is a level 2 user agent if, additionally:
+
+        * It allows the user to express all form field values
+        specified in an HTML document and to (attempt to) submit the
+        values as requests to information services.

+
+2. Terms
+
+    absolute URI
+            a URI in absolute form; for example, as per [URL]
+
+    anchor
+            one of two ends of a hyperlink; typically, a phrase
+            marked as an <A> element.
+
+    base URI
+            an absolute URI used in combination with a relative URI
+            to determine another absolute URI.
+
+    character
+            An atom of information, for example a letter or a digit.
+            Graphic characters have associated glyphs, whereas
+            control characters have associated processing semantics.
+
+    character encoding
+    scheme
+            A function whose domain is the set of sequences of
+            octets, and whose range is the set of sequences of
+            characters from a character repertoire; that is, a
+            sequence of octets and a character encoding scheme
+            determines a sequence of characters.
+
+    character repertoire
+            A finite set of characters; e.g. the range of a coded
+            character set.
+
+    code position
+            An integer. A coded character set and a code position
+            from its domain determine a character.
+
+    coded character set
+            A function whose domain is a subset of the integers and
+            whose range is a character repertoire. That is, for some
+            set of integers (usually of the form {0, 1, 2, ..., N}
+            ), a coded character set and an integer in that set
+            determine a character. Conversely, a character and a
+            coded character set determine the character's code
+            position (or, in rare cases, a few code positions).
+
+    conforming HTML user
+    agent
+            A user agent that conforms to this specification in its
+            processing of the Internet Media Type `text/html'.

+            the network or stored in a file. [SGML]
+
+    typical
+            Typical processing is described for many elements. This

+            uses for which the elements were intended.
+
+    URI
+            A Uniform Resource Identifier is a formatted string that
+            serves as an identifier for a resource, typically on the
+            Internet. URIs are used in HTML to identify the anchors
+            of hyperlinks. URIs in common practice include Uniform
+            Resource Locators (URLs)[URL] and Relative URLs
+            [RELURL].
+
+    user agent
+            A component of a distributed system that presents an
+            interface and processes requests on behalf of a user;
+            for example, a www browser or a mail user agent.

+    WWW
+            The World-Wide Web is a hypertext-based, distributed

+
+3. HTML as an Application of SGML
+
+   HTML is an application of ISO 8879:1986 -- Standard Generalized
+   Markup Language (SGML). SGML is a system for defining structured
+   document types and markup languages to represent instances of those
+   document types[SGML]. The public text -- DTD and SGML declaration --
+   of the HTML document type definition are provided in 9, "HTML Public
+   Text".
+
+   The term "HTML" refers to both the document type defined here and the
+   markup language for representing instances of this document type.
+
+3.1. SGML Documents
+
+   An HTML document is an SGML document; that is, a sequence of
+   characters organized physically into a set of entities, and logically
+   as a hierarchy of elements.
+
+   In the SGML specification, the first production of the SGML syntax
+   grammar separates an SGML document into three parts: an SGML
+   declaration, a prologue, and an instance. For the purposes of this
+   specification, the prologue is a DTD. This DTD describes another
+   grammar: the start symbol is given in the doctype declaration, the
+   terminals are data characters and tags, and the productions are
+   determined by the element declarations. The instance must conform to
+   the DTD, that is, it must be in the language defined by this grammar.
+
+   The SGML declaration determines the lexicon of the grammar. It
+   specifies the document character set, which determines a character
+   repertoire that contains all characters that occur in all text
+   entities in the document, and the code positions associated with
+   those characters.
+
+   The SGML declaration also specifies the syntax-reference character
+   set of the document, and a few other parameters that bind the
+   abstract syntax of SGML to a concrete syntax. This concrete syntax
+   determines how the sequence of characters of the document is mapped
+   to a sequence of terminals in the grammar of the prologue.

+
+
+   For example, consider the following document:
+
+    <!DOCTYPE html PUBLIC "-//IETF//DTD HTML 2.0//EN">
+    <title>Parsing Example</title>
+    <p>Some text. <em>&#42;wow&#42;</em></p>
+
+   An HTML user agent should use the SGML declaration that is given in
+   9.5, "SGML Declaration for HTML". According to its document character
+   set, `&#42;' refers to an asterisk character, `*'.
+
+   The instance above is regarded as the following sequence of
+   terminals:
+
+        1. start-tag: TITLE
+
+        2. data characters: "Parsing Example"
+
+        3. end-tag: TITLE
+
+        4. start-tag: P
+
+        5. data characters "Some text."
+
+        6. start-tag: EM
+
+        7. data characters: "*wow*"
+
+        8. end-tag: EM
+
+        9. end-tag: P

+
+
+   The start symbol of the DTD grammar is HTML, and the productions are
+   given in the public text identified by `-//IETF//DTD HTML 2.0//EN'
+   (9.1, "HTML DTD"). The terminals above parse as:
+
+       HTML
+        |
+        \-HEAD
+        |  |
+        |  \-TITLE
+        |      |
+        |      \-<TITLE>
+        |      |
+        |      \-"Parsing Example"
+        |      |
+        |      \-</TITLE>
+        |
+        \-BODY
+          |
+          \-P
+            |
+            \-<P>
+            |
+            \-"Some text. "
+            |
+            \-EM
+            |  |
+            |  \-<EM>
+            |  |
+            |  \-"*wow*"
+            |  |
+            |  \-</EM>
+            |
+            \-</P>
+
+   Some of the elements are delimited explicitly by tags, while the
+   boundaries of others are inferred. The <HTML> element contains a
+   <HEAD> element and a <BODY> element. The <HEAD> contains <TITLE>,
+   which is explicitly delimited by start- and end-tags.
+
+3.2. HTML Lexical Syntax
+
+   SGML specifies an abstract syntax and a reference concrete syntax.
+   Aside from certain quantities and capacities (e.g. the limit on the
+   length of a name), all HTML documents use the reference concrete
+   syntax. In particular, all markup characters are in the repertoire of
+   [ISO-646]. Data characters are drawn from the document character set
+   (see 6, "Characters, Words, and Paragraphs").

+RFC 1866            Hypertext Markup Language - 2.0        November 1995
+
+
+   A complete discussion of SGML parsing, e.g. the mapping of a sequence
+   of characters to a sequence of tags and data, is left to the SGML
+   standard[SGML]. This section is only a summary.
+
+3.2.1. Data Characters
+
+   Any sequence of characters that do not constitute markup (see 9.6
+   "Delimiter Recognition" of [SGML]) are mapped directly to strings of
+   data characters. Some markup also maps to data character strings.
+   Numeric character references map to single-character strings, via the
+   document character set. Each reference to one of the general entities
+   defined in the HTML DTD maps to a single-character string.
+
+   For example,
+
+    abc&lt;def    => "abc","<","def"
+    abc&#60;def   => "abc","<","def"
+
+   The terminating semicolon on entity or numeric character references
+   is only necessary when the character following the reference would
+   otherwise be recognized as part of the name (see 9.4.5 "Reference
+   End" in [SGML]).
+
+    abc &lt def     => "abc ","<"," def"
+    abc &#60 def    => "abc ","<"," def"
+
+   An ampersand is only recognized as markup when it is followed by a
+   letter or a `#' and a digit:
+
+    abc & lt def    => "abc & lt def"
+    abc &# 60 def    => "abc &# 60 def"
+
+   A useful technique for translating plain text to HTML is to replace
+   each '<', '&', and '>' by an entity reference or numeric character
+   reference as follows:
+
+                     ENTITY      NUMERIC
+           CHARACTER REFERENCE   CHAR REF     CHARACTER DESCRIPTION
+           --------- ----------  -----------  ---------------------
+             &       &amp;       &#38;        Ampersand
+             <       &lt;        &#60;        Less than
+             >       &gt;        &#62;        Greater than
+
+        NOTE - There are SGML mechanisms, CDATA and RCDATA
+        declared content, that allow most `<', `>', and `&'
+        characters to be entered without the use of entity
+        references. Because these mechanisms tend to be used and
+        implemented inconsistently, and because they conflict
+

+
+
+        with techniques for reducing HTML to 7 bit ASCII for
+        transport, they are deprecated in this version of HTML.
+        See 5.5.2.1, "Example and Listing: XMP, LISTING".
+
+3.2.2. Tags
+
+   Tags delimit elements such as headings, paragraphs, lists, character
+   highlighting, and links. Most HTML elements are identified in a
+   document as a start-tag, which gives the element name and attributes,
+   followed by the content, followed by the end tag. Start-tags are
+   delimited by `<' and `>'; end tags are delimited by `</' and `>'. An
+   example is:
+
+   <H1>This is a Heading</H1>
+
+   Some elements only have a start-tag without an end-tag. For example,
+   to create a line break, use the `<BR>' tag.  Additionally, the end
+   tags of some other elements, such as Paragraph (`</P>'), List Item
+   (`</LI>'), Definition Term (`</DT>'), and Definition Description
+   (`</DD>') elements, may be omitted.
+
+   The content of an element is a sequence of data character strings and
+   nested elements. Some elements, such as anchors, cannot be nested.
+   Anchors and character highlighting may be put inside other
+   constructs. See the HTML DTD, 9.1, "HTML DTD" for full details.
+
+      NOTE - The SGML declaration for HTML specifies SHORTTAG YES, which
+      means that there are other valid syntaxes for tags, such as NET
+      tags, `<EM/.../'; empty start tags, `<>'; and empty end-tags,
+      `</>'. Until support for these idioms is widely deployed, their
+      use is strongly discouraged.
+
+3.2.3. Names
+
+   A name consists of a letter followed by letters, digits, periods, or
+   hyphens. The length of a name is limited to 72 characters by the
+   `NAMELEN' parameter in the SGML declaration for HTML, 9.5, "SGML
+   Declaration for HTML". Element and attribute names are not case
+   sensitive, but entity names are.  For example, `<BLOCKQUOTE>',
+   `<BlockQuote>', and `<blockquote>' are equivalent, whereas `&amp;' is
+   different from `&AMP;'.
+
+   In a start-tag, the element name must immediately follow the tag open
+   delimiter `<'.
+
+
+

+
+RFC 1866            Hypertext Markup Language - 2.0        November 1995
+
+
+3.2.4. Attributes
+
+   In a start-tag, white space and attributes are allowed between the
+   element name and the closing delimiter. An attribute specification
+   typically consists of an attribute name, an equal sign, and a value,
+   though some attribute specifications may be just a name token. White
+   space is allowed around the equal sign.
+
+   The value of the attribute may be either:
+
+        * A string literal, delimited by single quotes or double
+        quotes and not containing any occurrences of the delimiting
+        character.
+
+            NOTE - Some historical implementations consider any
+            occurrence of the `>' character to signal the end of
+            a tag. For compatibility with such implementations,
+            when `>' appears in an attribute value, it should be
+            represented with a numeric character reference. For
+            example, `<IMG SRC="eq1.jpg" alt="a>b">' should be
+            written `<IMG SRC="eq1.jpg" alt="a&#62;b">' or `<IMG
+            SRC="eq1.jpg" alt="a&gt;b">'.
+
+        * A name token (a sequence of letters, digits, periods, or
+        hyphens). Name tokens are not case sensitive.
+
+            NOTE - Some historical implementations allow any
+            character except space or `>' in a name token.
+
+   In this example, <img> is the element name, src is the attribute
+   name, and `http://host/dir/file.gif' is the attribute value:
+
+   <img src='http://host/dir/file.gif'>
+
+   A useful technique for computing an attribute value literal for a
+   given string is to replace each quote and white space character by an
+   entity reference or numeric character reference as follows:
+
+                     ENTITY      NUMERIC
+           CHARACTER REFERENCE   CHAR REF     CHARACTER DESCRIPTION
+           --------- ----------  -----------  ---------------------
+             HT                  &#9;         Tab
+             LF                  &#10;        Line Feed
+             CR                  &#13;        Carriage Return
+             SP                  &#32;        Space
+             "       &quot;      &#34;        Quotation mark
+             &       &amp;       &#38;        Ampersand
+
+

+
+RFC 1866            Hypertext Markup Language - 2.0        November 1995
+
+
+   For example:
+
+   <IMG SRC="image.jpg" alt="First &quot;real&quot; example">
+
+   The `NAMELEN' parameter in the SGML declaration (9.5, "SGML
+   Declaration for HTML") limits the length of an attribute value to
+   1024 characters.
+
+   Attributes such as ISMAP and COMPACT may be written using a minimized
+   syntax (see 7.9.1.2 "Omitted Attribute Name" in [SGML]). The markup:
+
+   <UL COMPACT="compact">
+
+   can be written using a minimized syntax:
+
+   <UL COMPACT>
+
+   NOTE - Some historical implementations only understand the minimized
+   syntax.
+
+3.2.5. Comments
+
+   To include comments in an HTML document, use a comment declaration. A
+   comment declaration consists of `<!' followed by zero or more
+   comments followed by `>'. Each comment starts with `--' and includes
+   all text up to and including the next occurrence of `--'. In a
+   comment declaration, white space is allowed after each comment, but
+   not before the first comment.  The entire comment declaration is
+   ignored.
+
+      NOTE - Some historical HTML implementations incorrectly consider
+      any `>' character to be the termination of a comment.
+
+   For example:
+
+    <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
+    <HEAD>
+    <TITLE>HTML Comment Example</TITLE>
+    <!-- Id: html-sgml.sgm,v 1.5 1995/05/26 21:29:50 connolly Exp  -->
+    <!-- another -- -- comment -->
+    <!>
+    </HEAD>
+    <BODY>
+    <p> <!- not a comment, just regular old data characters ->

+
+
+3.3. HTML Public Text Identifiers
+
+   To identify information as an HTML document conforming to this
+   specification, each document must start with one of the following
+   document type declarations.
+
+   <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
+
+   This document type declaration refers to the HTML DTD in 9.1, "HTML
+   DTD".
+
+      NOTE - If the body of a `text/html' message entity does not begin
+      with a document type declaration, an HTML user agent should infer
+      the above document type declaration.
+
+   <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0 Level 2//EN">
+
+   This document type declaration also refers to the HTML DTD which
+   appears in 9.1, "HTML DTD".
+
+   <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0 Level 1//EN">
+
+   This document type declaration refers to the level 1 HTML DTD in 9.3,
+   "Level 1 HTML DTD". Form elements must not occur in level 1
+   documents.
+
+   <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0 Strict//EN">
+   <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0 Strict Level 1//EN">
+
+   These two document type declarations refer to the HTML DTD in 9.2,
+   "Strict HTML DTD" and 9.4, "Strict Level 1 HTML DTD". They refer to
+   the more structurally rigid definition of HTML.
+
+   HTML user agents may support other document types. In particular,
+   they may support other formal public identifiers, or other document
+   types altogether. They may support an internal declaration subset
+   with supplemental entity, element, and other markup declarations.
+
+3.4. Example HTML Document
+
+    <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
+    <HTML>
+    <!-- Here's a good place to put a comment. -->
+    <HEAD>
+    <TITLE>Structural Example</TITLE>

+    <LI>Third item in an ordered list.

+    <P>This is an additional paragraph. Technically, end tags are

+
+4. HTML as an Internet Media Type
+
+   An HTML user agent allows users to interact with resources which have
+   HTML representations. At a minimum, it must allow users to examine
+   and navigate the content of HTML level 1 documents. HTML user agents
+   should be able to preserve all formatting distinctions represented in
+   an HTML document, and be able to simultaneously present resources
+   referred to by IMG elements (they may ignore some formatting
+   distinctions or IMG resources at the request of the user). Level 2
+   HTML user agents should support form entry and submission.
+
+4.1. text/html media type
+
+   This specification defines the Internet Media Type [IMEDIA] (formerly
+   referred to as the Content Type [MIME]) called `text/html'. The
+   following is to be registered with [IANA].
+
+    Media Type name
+            text

+
+
+    Optional parameters
+            level, charset
+
+    Encoding considerations
+            any encoding is allowed
+
+    Security considerations
+            see 10, "Security Considerations"
+
+    The optional parameters are defined as follows:
+
+    Level
+            The level parameter specifies the feature set used in
+            the document. The level is an integer number, implying
+            that any features of same or lower level may be present
+            in the document. Level 1 is all features defined in this
+            specification except those that require the <FORM>
+            element. Level 2 includes form processing. Level 2 is
+            the default.
+
+    Charset
+            The charset parameter (as defined in section 7.1.1 of
+            RFC 1521[MIME]) may be given to specify the character
+            encoding scheme used to represent the HTML document as a
+            sequence of octets. The default value is outside the
+            scope of this specification; but for example, the
+            default is `US-ASCII' in the context of MIME mail, and
+            `ISO-8859-1' in the context of HTTP [HTTP].
+
+4.2. HTML Document Representation
+
+   A message entity with a content type of `text/html' represents an
+   HTML document, consisting of a single text entity. The `charset'
+   parameter (whether implicit or explicit) identifies a character
+   encoding scheme. The text entity consists of the characters
+   determined by this character encoding scheme and the octets of the
+   body of the message entity.
+
+4.2.1. Undeclared Markup Error Handling
+
+   To facilitate experimentation and interoperability between
+   implementations of various versions of HTML, the installed base of
+   HTML user agents supports a superset of the HTML 2.0 language by
+   reducing it to HTML 2.0: markup in the form of a start-tag or end-
+   tag, whose generic identifier is not declared is mapped to nothing
+   during tokenization. Undeclared attributes are treated similarly. The
+   entire attribute specification of an unknown attribute (i.e., the
+   unknown attribute and its value, if any) should be ignored. On the
+

+
+
+   other hand, references to undeclared entities should be treated as
+   data characters.
+
+   For example:
+
+    <div class=chapter><h1>foo</h1><p>...</div>
+      => <H1>,"foo",</H1>,<P>,"..."
+    xxx <P ID=z23> yyy
+      => "xxx ",<P>," yyy
+    Let &alpha; &amp; &beta; be finite sets.
+      => "Let &alpha; & &beta; be finite sets."
+
+   Support for notifying the user of such errors is encouraged.
+
+   Information providers are warned that this convention is not binding:
+   unspecified behavior may result, as such markup does not conform to
+   this specification.
+
+4.2.2. Conventional Representation of Newlines
+
+   SGML specifies that a text entity is a sequence of records, each
+   beginning with a record start character and ending with a record end
+   character (code positions 10 and 13 respectively) (section 7.6.1,
+   "Record Boundaries" in [SGML]).
+
+   [MIME] specifies that a body of type `text/*' is a sequence of lines,
+   each terminated by CRLF, that is, octets 13, 10.
+
+   In practice, HTML documents are frequently represented and
+   transmitted using an end of line convention that depends on the
+   conventions of the source of the document; frequently, that
+   representation consists of CR only, LF only, or a CR LF sequence.
+   Hence the decoding of the octets will often result in a text entity
+   with some missing record start and record end characters.
+
+   Since there is no ambiguity, HTML user agents are encouraged to infer
+   the missing record start and end characters.
+
+   An HTML user agent should treat end of line in any of its variations
+   as a word space in all contexts except preformatted text. Within
+   preformatted text, an HTML user agent should treat any of the three
+   common representations of end-of-line as starting a new line.
+
+5. Document Structure
+
+   An HTML document is a tree of elements, including a head and body,
+   headings, paragraphs, lists, etc. Form elements are discussed in 8,
+   "Forms".

+
+
+5.1. Document Element: HTML
+
+   The HTML document element consists of a head and a body, much like a
+   memo or a mail message. The head contains the title and optional
+   elements. The body is a text flow consisting of paragraphs, lists,
+   and other elements.
+
+5.2. Head: HEAD
+
+   The head of an HTML document is an unordered collection of
+   information about the document. For example:
+
+    <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
+    <HEAD>
+    <TITLE>Introduction to HTML</TITLE>
+    </HEAD>
+    ...
+
+5.2.1. Title: TITLE
+
+   Every HTML document must contain a <TITLE> element.
+
+   The title should identify the contents of the document in a global
+   context. A short title, such as "Introduction" may be meaningless out
+   of context. A title such as "Introduction to HTML Elements" is more
+   appropriate.
+
+      NOTE - The length of a title is not limited; however, long titles
+      may be truncated in some applications. To minimize this
+      possibility, titles should be fewer than 64 characters.
+
+   A user agent may display the title of a document in a history list or
+   as a label for the window displaying the document. This differs from
+   headings (5.4, "Headings: H1 ... H6"), which are typically displayed
+   within the body text flow.
+
+5.2.2. Base Address: BASE
+
+   The optional <BASE> element provides a base address for interpreting
+   relative URLs when the document is read out of context (see 7,
+   "Hyperlinks"). The value of the HREF attribute must be an absolute
+   URI.
+
+5.2.3. Keyword Index: ISINDEX
+
+   The <ISINDEX> element indicates that the user agent should allow the
+   user to search an index by giving keywords. See 7.5, "Queries and
+   Indexes" for details.
+

+
+RFC 1866            Hypertext Markup Language - 2.0        November 1995
+
+
+5.2.4. Link: LINK
+
+   The <LINK> element represents a hyperlink (see 7, "Hyperlinks").  Any
+   number of LINK elements may occur in the <HEAD> element of an HTML
+   document. It has the same attributes as the <A> element (see 5.7.3,
+   "Anchor: A").
+
+   The <LINK> element is typically used to indicate authorship, related
+   indexes and glossaries, older or more recent versions, document
+   hierarchy, associated resources such as style sheets, etc.
+
+5.2.5. Associated Meta-information: META
+
+   The <META> element is an extensible container for use in identifying
+   specialized document meta-information.  Meta-information has two main
+   functions:
+
+        * to provide a means to discover that the data set exists
+        and how it might be obtained or accessed; and
+
+        * to document the content, quality, and features of a data
+        set, indicating its fitness for use.
+
+   Each <META> element specifies a name/value pair. If multiple META
+   elements are provided with the same name, their combined contents--
+   concatenated as a comma-separated list--is the value associated with
+   that name.
+
+        NOTE - The <META> element should not be used where a
+        specific element, such as <TITLE>, would be more
+        appropriate. Rather than a <META> element with a URI as
+        the value of the CONTENT attribute, use a <LINK>
+        element.
+
+   HTTP servers may read the content of the document <HEAD> to generate
+   header fields corresponding to any elements defining a value for the
+   attribute HTTP-EQUIV.
+
+        NOTE - The method by which the server extracts document
+        meta-information is unspecified and not mandatory. The
+        <META> element only provides an extensible mechanism for
+        identifying and embedding document meta-information --
+        how it may be used is up to the individual server
+        implementation and the HTML user agent.

+
+
+    Attributes of the META element:
+
+    HTTP-EQUIV
+            binds the element to an HTTP header field. An HTTP
+            server may use this information to process the document.
+            In particular, it may include a header field in the
+            responses to requests for this document: the header name
+            is taken from the HTTP-EQUIV attribute value, and the
+            header value is taken from the value of the CONTENT
+            attribute. HTTP header names are not case sensitive.
+
+    NAME
+            specifies the name of the name/value pair. If not
+            present, HTTP-EQUIV gives the name.
+
+    CONTENT
+            specifies the value of the name/value pair.
+
+    Examples
+
+    If the document contains:
+
+    <META HTTP-EQUIV="Expires"
+          CONTENT="Tue, 04 Dec 1993 21:29:02 GMT">
+    <meta http-equiv="Keywords" CONTENT="Fred">
+    <META HTTP-EQUIV="Reply-to"
+          content="fielding@ics.uci.edu (Roy Fielding)">
+    <Meta Http-equiv="Keywords" CONTENT="Barney">
+
+    then the server may include the following header fields:
+
+    Expires: Tue, 04 Dec 1993 21:29:02 GMT
+    Keywords: Fred, Barney
+    Reply-to: fielding@ics.uci.edu (Roy Fielding)
+
+    as part of the HTTP response to a `GET' or `HEAD' request for
+    that document.
+
+    An HTTP server must not use the <META> element to form an HTTP
+    response header unless the HTTP-EQUIV attribute is present.
+
+    An HTTP server may disregard any <META> elements that specify
+    information controlled by the HTTP server, for example `Server',
+
+    `Date', and `Last-modified'.

+
+
+5.2.6. Next Id: NEXTID
+
+   The <NEXTID> element is included for historical reasons only.  HTML
+   documents should not contain <NEXTID> elements.
+
+   The <NEXTID> element gives a hint for the name to use for a new <A>
+   element when editing an HTML document. It should be distinct from all
+   NAME attribute values on <A> elements. For example:
+
+   <NEXTID N=Z27>
+
+5.3. Body: BODY
+
+   The <BODY> element contains the text flow of the document, including
+   headings, paragraphs, lists, etc.
+
+   For example:
+
+    <BODY>
+    <h1>Important Stuff</h1>
+    <p>Explanation about important stuff...
+    </BODY>
+
+5.4. Headings: H1 ... H6
+
+   The six heading elements, <H1> through <H6>, denote section headings.
+   Although the order and occurrence of headings is not constrained by
+   the HTML DTD, documents should not skip levels (for example, from H1
+   to H3), as converting such documents to other representations is
+   often problematic.
+
+   Example of use:
+
+    <H1>This is a heading</H1>
+    Here is some text
+    <H2>Second level heading</H2>
+    Here is some more text.
+
+    Typical renderings are:
+
+    H1
+            Bold, very-large font, centered. One or two blank lines
+            above and below.
+
+    H2
+            Bold, large font, flush-left. One or two blank lines
+            above and below.

+
+    H3
+            Italic, large font, slightly indented from the left
+            margin. One or two blank lines above and below.
+
+    H4
+            Bold, normal font, indented more than H3. One blank line
+            above and below.
+
+    H5
+            Italic, normal font, indented as H4. One blank line
+            above.
+
+    H6
+            Bold, indented same as normal text, more than H5. One
+            blank line above.
+
+5.5. Block Structuring Elements
+
+   Block structuring elements include paragraphs, lists, and block
+   quotes. They must not contain heading elements, but they may contain
+   phrase markup, and in some cases, they may be nested.
+
+5.5.1. Paragraph: P
+
+   The <P> element indicates a paragraph. The exact indentation, leading
+   space, etc. of a paragraph is not specified and may be a function of
+   other tags, style sheets, etc.
+
+   Typically, paragraphs are surrounded by a vertical space of one line
+   or half a line. The first line in a paragraph is indented in some
+   cases.
+
+   Example of use:
+
+    <H1>This Heading Precedes the Paragraph</H1>
+    <P>This is the text of the first paragraph.
+    <P>This is the text of the second paragraph. Although you do not
+    need to start paragraphs on new lines, maintaining this
+    convention facilitates document maintenance.</P>
+    <P>This is the text of a third paragraph.</P>
+
+5.5.2. Preformatted Text: PRE
+
+   The <PRE> element represents a character cell block of text and is
+   suitable for text that has been formatted for a monospaced font.
+
+   The <PRE> tag may be used with the optional WIDTH attribute. The
+   WIDTH attribute specifies the maximum number of characters for a line
+
+
+
+Berners-Lee & Connolly      Standards Track                    [Page 25]

+RFC 1866            Hypertext Markup Language - 2.0        November 1995
+
+
+   and allows the HTML user agent to select a suitable font and
+   indentation.
+
+   Within preformatted text:
+
+        * Line breaks within the text are rendered as a move to the
+        beginning of the next line.
+
+            NOTE - References to the "beginning of a new line"
+            do not imply that the renderer is forbidden from
+            using a constant left indent for rendering
+            preformatted text. The left indent may be
+            constrained by the width required.
+
+        * Anchor elements and phrase markup may be used.
+
+            NOTE - Constraints on the processing of <PRE>
+            content may limit or prevent the ability of the HTML
+            user agent to faithfully render phrase markup.
+
+        * Elements that define paragraph formatting (headings,
+        address, etc.) must not be used.
+
+            NOTE - Some historical documents contain <P> tags in
+            <PRE> elements. User agents are encouraged to treat
+            this as a line break. A <P> tag followed by a
+            newline character should produce only one line
+            break, not a line break plus a blank line.
+
+        * The horizontal tab character (code position 9 in the HTML
+        document character set) must be interpreted as the smallest
+        positive nonzero number of spaces which will leave the
+        number of characters so far on the line as a multiple of 8.
+        Documents should not contain tab characters, as they are not
+        supported consistently.
+
+    Example of use:
+
+    <PRE>
+    Line 1.
+           Line 2 is to the right of line 1.     <a href="abc">abc</a>
+           Line 3 aligns with line 2.            <a href="def">def</a>

+
+
+5.5.2.1. Example and Listing: XMP, LISTING
+
+   The <XMP> and <LISTING> elements are similar to the <PRE> element,
+   but they have a different syntax. Their content is declared as CDATA,
+   which means that no markup except the end-tag open delimiter-in-
+   context is recognized (see 9.6 "Delimiter Recognition" of [SGML]).
+
+      NOTE - In a previous draft of the HTML specification, the syntax
+      of <XMP> and <LISTING> elements allowed closing tags to be treated
+      as data characters, as long as the tag name was not <XMP> or
+      <LISTING>, respectively.
+
+   Since CDATA declared content has a number of unfortunate interactions
+   with processing techniques and tends to be used and implemented
+   inconsistently, HTML documents should not contain <XMP> nor <LISTING>
+   elements -- the <PRE> tag is more expressive and more consistently
+   supported.
+
+   The <LISTING> element should be rendered so that at least 132
+   characters fit on a line. The <XMP> element should be rendered so
+   that at least 80 characters fit on a line but is otherwise identical
+   to the <LISTING> element.
+
+      NOTE - In a previous draft, HTML included a <PLAINTEXT> element
+      that is similar to the <LISTING> element, except that there is no
+      closing tag: all characters after the <PLAINTEXT> start-tag are
+      data.
+
+5.5.3. Address: ADDRESS
+
+   The <ADDRESS> element contains such information as address, signature
+   and authorship, often at the beginning or end of the body of a
+   document.
+
+   Typically, the <ADDRESS> element is rendered in an italic typeface
+   and may be indented.
+
+   Example of use:
+
+    <ADDRESS>
+    Newsletter editor<BR>
+    J.R. Brown<BR>
+    JimquickPost News, Jimquick, CT 01234<BR>
+    Tel (123) 456 7890

+
+
+5.5.4. Block Quote: BLOCKQUOTE
+
+   The <BLOCKQUOTE> element contains text quoted from another source.
+
+   A typical rendering might be a slight extra left and right indent,
+   and/or italic font. The <BLOCKQUOTE> typically provides space above
+   and below the quote.
+
+   Single-font rendition may reflect the quotation style of Internet
+   mail by putting a vertical line of graphic characters, such as the
+   greater than symbol (>), in the left margin.
+
+   Example of use:
+
+    I think the play ends
+    <BLOCKQUOTE>
+    <P>Soft you now, the fair Ophelia. Nymph, in thy orisons, be all
+    my sins remembered.
+    </BLOCKQUOTE>
+    but I am not sure.
+
+5.6. List Elements
+
+   HTML includes a number of list elements. They may be used in
+   combination; for example, a <OL> may be nested in an <LI> element of
+   a <UL>.
+
+   The COMPACT attribute suggests that a compact rendering be used.
+
+5.6.1. Unordered List: UL, LI
+
+   The <UL> represents a list of items -- typically rendered as a
+   bulleted list.
+
+   The content of a <UL> element is a sequence of <LI> elements.  For
+   example:
+
+    <UL>
+    <LI>First list item
+    <LI>Second list item
+     <p>second paragraph of second item
+    <LI>Third list item
+    </UL>
+
+5.6.2. Ordered List: OL
+
+   The <OL> element represents an ordered list of items, sorted by
+   sequence or order of importance. It is typically rendered as a

+
+
+   numbered list.
+
+   The content of a <OL> element is a sequence of <LI> elements.  For
+   example:
+
+    <OL>
+    <LI>Click the Web button to open URI window.
+    <LI>Enter the URI number in the text field of the Open URI
+    window. The Web document you specified is displayed.
+      <ol>
+       <li>substep 1
+       <li>substep 2
+      </ol>
+    <LI>Click highlighted text to move from one link to another.
+    </OL>
+
+5.6.3. Directory List: DIR
+
+   The <DIR> element is similar to the <UL> element. It represents a
+   list of short items, typically up to 20 characters each. Items in a
+   directory list may be arranged in columns, typically 24 characters
+   wide.
+
+   The content of a <DIR> element is a sequence of <LI> elements.
+   Nested block elements are not allowed in the content of <DIR>
+   elements. For example:
+
+    <DIR>
+    <LI>A-H<LI>I-M
+    <LI>M-R<LI>S-Z
+    </DIR>
+
+5.6.4. Menu List: MENU
+
+   The <MENU> element is a list of items with typically one line per
+   item. The menu list style is typically more compact than the style of
+   an unordered list.
+
+   The content of a <MENU> element is a sequence of <LI> elements.
+   Nested block elements are not allowed in the content of <MENU>
+   elements. For example:
+
+    <MENU>
+    <LI>First item in the list.
+    <LI>Second item in the list.
+    <LI>Third item in the list.

+
+
+5.6.5. Definition List: DL, DT, DD
+
+   A definition list is a list of terms and corresponding definitions.
+   Definition lists are typically formatted with the term flush-left and
+   the definition, formatted paragraph style, indented after the term.
+
+   The content of a <DL> element is a sequence of <DT> elements and/or
+   <DD> elements, usually in pairs. Multiple <DT> may be paired with a
+   single <DD> element. Documents should not contain multiple
+   consecutive <DD> elements.
+
+   Example of use:
+
+    <DL>
+    <DT>Term<DD>This is the definition of the first term.
+    <DT>Term<DD>This is the definition of the second term.
+    </DL>
+
+   If the DT term does not fit in the DT column (typically one third of
+   the display area), it may be extended across the page with the DD
+   section moved to the next line, or it may be wrapped onto successive
+   lines of the left hand column.
+
+   The optional COMPACT attribute suggests that a compact rendering be
+   used, because the list items are small and/or the entire list is
+   large.
+
+   Unless the COMPACT attribute is present, an HTML user agent may leave
+   white space between successive DT, DD pairs. The COMPACT attribute
+   may also reduce the width of the left-hand (DT) column.
+
+    <DL COMPACT>
+    <DT>Term<DD>This is the first definition in compact format.
+    <DT>Term<DD>This is the second definition in compact format.
+    </DL>
+
+5.7. Phrase Markup
+
+   Phrases may be marked up according to idiomatic usage, typographic
+   appearance, or for use as hyperlink anchors.
+
+   User agents must render highlighted phrases distinctly from plain
+   text. Additionally, <EM> content must be rendered as distinct from
+   <STRONG> content, and <B> content must rendered as distinct from <I>
+   content.
+
+   Phrase elements may be nested within the content of other phrase
+   elements; however, HTML user agents may render nested phrase elements

+
+
+   indistinctly from non-nested elements:
+
+   plain <B>bold <I>italic</I></B> may be rendered
+   the same as plain <B>bold </B><I>italic</I>
+
+5.7.1. Idiomatic Elements
+
+   Phrases may be marked up to indicate certain idioms.
+
+      NOTE - User agents may support the <DFN> element, not included in
+      this specification, as it has been deployed to some extent. It is
+      used to indicate the defining instance of a term, and it is
+      typically rendered in italic or bold italic.
+
+5.7.1.1. Citation: CITE
+
+      The <CITE> element is used to indicate the title of a book or
+      other citation. It is typically rendered as italics. For example:
+
+      He just couldn't get enough of <cite>The Grapes of Wrath</cite>.
+
+5.7.1.2. Code: CODE
+
+      The <CODE> element indicates an example of code, typically
+      rendered in a mono-spaced font. The <CODE> element is intended for
+      short words or phrases of code; the <PRE> block structuring
+      element (5.5.2, "Preformatted Text: PRE") is more appropriate
+       for multiple-line listings. For example:
+
+      The expression <code>x += 1</code>
+      is short for <code>x = x + 1</code>.
+
+5.7.1.3. Emphasis: EM
+
+      The <EM> element indicates an emphasized phrase, typically
+      rendered as italics. For example:
+
+      A singular subject <em>always</em> takes a singular verb.
+
+5.7.1.4. Keyboard: KBD
+
+      The <KBD> element indicates text typed by a user, typically
+      rendered in a mono-spaced font. This is commonly used in
+      instruction manuals. For example:
+
+      Enter <kbd>FIND IT</kbd> to search the database.

+
+
+5.7.1.5. Sample: SAMP
+
+      The <SAMP> element indicates a sequence of literal characters,
+      typically rendered in a mono-spaced font. For example:
+
+      The only word containing the letters <samp>mt</samp> is dreamt.
+
+5.7.1.6. Strong Emphasis: STRONG
+
+      The <STRONG> element indicates strong emphasis, typically rendered
+      in bold. For example:
+
+      <strong>STOP</strong>, or I'll say "<strong>STOP</strong>" again!
+
+5.7.1.7. Variable: VAR
+
+      The <VAR> element indicates a placeholder variable, typically
+      rendered as italic. For example:
+
+      Type <SAMP>html-check <VAR>file</VAR> | more</SAMP>
+      to check <VAR>file</VAR> for markup errors.
+
+5.7.2. Typographic Elements
+
+      Typographic elements are used to specify the format of marked
+      text.
+
+      Typical renderings for idiomatic elements may vary between user
+      agents. If a specific rendering is necessary -- for example, when
+      referring to a specific text attribute as in "The italic parts are
+      mandatory" -- a typographic element can be used to ensure that the
+      intended typography is used where possible.
+
+      NOTE - User agents may support some typographic elements not
+      included in this specification, as they have been deployed to some
+      extent. The <STRIKE> element indicates horizontal line through the
+      characters, and the <U> element indicates an underline.
+
+5.7.2.1. Bold: B
+
+   The <B> element indicates bold text. Where bold typography is
+   unavailable, an alternative representation may be used.
+
+5.7.2.2. Italic: I
+
+   The <I> element indicates italic text. Where italic typography is
+   unavailable, an alternative representation may be used.

+RFC 1866            Hypertext Markup Language - 2.0        November 1995
+
+
+5.7.2.3. Teletype: TT
+
+   The <TT> element indicates teletype (monospaced )text. Where a
+   teletype font is unavailable, an alternative representation may be
+   used.
+
+5.7.3. Anchor: A
+
+   The <A> element indicates a hyperlink anchor (see 7, "Hyperlinks").
+   At least one of the NAME and HREF attributes should be present.
+   Attributes of the <A> element:
+
+    HREF
+            gives the URI of the head anchor of a hyperlink.
+
+    NAME
+            gives the name of the anchor, and makes it available as
+            a head of a hyperlink.
+
+    TITLE
+            suggests a title for the destination resource --
+            advisory only. The TITLE attribute may be used:
+
+                * for display prior to accessing the destination
+                resource, for example, as a margin note or on a
+                small box while the mouse is over the anchor, or
+                while the document is being loaded;
+
+                * for resources that do not include a title, such as
+                graphics, plain text and Gopher menus, for use as a
+                window title.
+
+    REL
+            The REL attribute gives the relationship(s) described by
+            the hyperlink. The value is a whitespace separated list
+            of relationship names. The semantics of link
+            relationships are not specified in this document.
+
+    REV
+            same as the REL attribute, but the semantics of the
+            relationship are in the reverse direction. A link from A
+            to B with REL="X" expresses the same relationship as a
+            link from B to A with REV="X". An anchor may have both
+            REL and REV attributes.
+
+    URN
+            specifies a preferred, more persistent identifier for
+            the head anchor of the hyperlink. The syntax and
+

+
+
+            semantics of the URN attribute are not yet specified.
+
+    METHODS
+            specifies methods to be used in accessing the
+            destination, as a whitespace-separated list of names.
+            The set of applicable names is a function of the scheme
+            of the URI in the HREF attribute. For similar reasons as
+            for the TITLE attribute, it may be useful to include the
+            information in advance in the link. For example, the
+            HTML user agent may chose a different rendering as a
+            function of the methods allowed; for example, something
+            that is searchable may get a different icon.
+
+5.8. Line Break: BR
+
+   The <BR> element specifies a line break between words (see 6,
+   "Characters, Words, and Paragraphs"). For example:
+
+    <P> Pease porridge hot<BR>
+    Pease porridge cold<BR>
+    Pease porridge in the pot<BR>
+    Nine days old.
+
+5.9. Horizontal Rule: HR
+
+   The <HR> element is a divider between sections of text; typically a
+   full width horizontal rule or equivalent graphic.  For example:
+
+    <HR>
+    <ADDRESS>February 8, 1995, CERN</ADDRESS>
+    </BODY>
+
+5.10. Image: IMG
+
+   The <IMG> element refers to an image or icon via a hyperlink (see
+   7.3, "Simultaneous Presentation of Image Resources").
+
+   HTML user agents may process the value of the ALT attribute as an
+   alternative to processing the image resource indicated by the SRC
+   attribute.
+
+      NOTE - Some HTML user agents can process graphics linked via
+      anchors, but not <IMG> graphics. If a graphic is essential, it
+      should be referenced from an <A> element rather than an <IMG>
+      element. If the graphic is not essential, then the <IMG> element
+      is appropriate.
+
+   Attributes of the <IMG> element:

+
+                NOTE - In practice, the media types of image
+                resources are limited to a few raster graphic
+                formats: typically `image/gif', `image/jpeg'. In

+6. Characters, Words, and Paragraphs
+
+   An HTML user agent should present the body of an HTML document as a
+   collection of typeset paragraphs and preformatted text.  Except for
+   preformatted elements (<PRE>, <XMP>, <LISTING>, <TEXTAREA>), each
+   block structuring element is regarded as a paragraph by taking the

+
+
+   data characters in its content and the content of its descendant
+   elements, concatenating them, and splitting the result into words,
+   separated by space, tab, or record end characters (and perhaps hyphen
+   characters). The sequence of words is typeset as a paragraph by
+   breaking it into lines.
+
+6.1. The HTML Document Character Set
+
+   The document character set specified in 9.5, "SGML Declaration for
+   HTML" must be supported by HTML user agents. It includes the graphic
+   characters of Latin Alphabet No. 1, or simply Latin-1.  Latin-1
+   comprises 191 graphic characters, including the alphabets of most
+   Western European languages.
+
+      NOTE - Use of the non-breaking space and soft hyphen indicator
+      characters is discouraged because support for them is not widely
+      deployed.
+
+      NOTE - To support non-western writing systems, a larger character
+      repertoire will be specified in a future version of HTML. The
+      document character set will be [ISO-10646], or some subset that
+      agrees with [ISO-10646]; in particular, all numeric character
+      references must use code positions assigned by [ISO-10646].
+
+   In SGML applications, the use of control characters is limited in
+   order to maximize the chance of successful interchange over
+   heterogeneous networks and operating systems. In the HTML document
+   character set only three control characters are allowed: Horizontal
+   Tab, Carriage Return, and Line Feed (code positions 9, 13, and 10).
+
+   The HTML DTD references the Added Latin 1 entity set, to allow
+   mnemonic representation of selected Latin 1 characters using only the
+   widely supported ASCII character repertoire. For example:
+
+   Kurt G&ouml;del was a famous logician and mathematician.
+
+   See 9.7.2, "ISO Latin 1 Character Entity Set" for a table of the
+   "Added Latin 1" entities, and 13, "The HTML Coded Character Set" for
+   a table of the code positions of [ISO 8859-1] and the control
+   characters in the HTML document character set.
+
+7. Hyperlinks
+
+   In addition to general purpose elements such as paragraphs and lists,
+   HTML documents can express hyperlinks. An HTML user agent allows the
+   user to navigate these hyperlinks.
+
+
+

+RFC 1866            Hypertext Markup Language - 2.0        November 1995
+
+
+   A hyperlink is a relationship between two anchors, called the head
+   and the tail of the hyperlink[DEXTER]. Anchors are identified by an
+   anchor address: an absolute Uniform Resource Identifier (URI),
+   optionally followed by a '#' and a sequence of characters called a
+   fragment identifier. For example:
+
+   http://www.w3.org/hypertext/WWW/TheProject.html
+   http://www.w3.org/hypertext/WWW/TheProject.html#z31
+
+   In an anchor address, the URI refers to a resource; it may be used in
+   a variety of information retrieval protocols to obtain an entity that
+   represents the resource, such as an HTML document. The fragment
+   identifier, if present, refers to some view on, or portion of the
+   resource.
+
+   Each of the following markup constructs indicates the tail anchor of
+   a hyperlink or set of hyperlinks:
+
+        * <A> elements with HREF present.
+
+        * <LINK> elements.
+
+        * <IMG> elements.
+
+        * <INPUT> elements with the SRC attribute present.
+
+        * <ISINDEX> elements.
+
+        * <FORM> elements with `METHOD=GET'.
+
+   These markup constructs refer to head anchors by a URI, either
+   absolute or relative, or a fragment identifier, or both.
+
+   In the case of a relative URI, the absolute URI in the address of the
+   head anchor is the result of combining the relative URI with a base
+   absolute URI as in [RELURL]. The base document is taken from the
+   document's <BASE> element, if present; else, it is determined as in
+   [RELURL].
+
+7.1. Accessing Resources
+
+   Once the address of the head anchor is determined, the user agent may
+   obtain a representation of the resource.
+
+   For example, if the base URI is `http://host/x/y.html' and the
+   document contains:
+
+   <img src="../icons/abc.gif">
+
+
+
+Berners-Lee & Connolly      Standards Track                    [Page 37]
+
+RFC 1866            Hypertext Markup Language - 2.0        November 1995
+
+
+   then the user agent uses the URI `http://host/icons/abc.gif' to
+   access the resource, as in [URL]..
+
+7.2. Activation of Hyperlinks
+
+   An HTML user agent allows the user to navigate the content of the
+   document and request activation of hyperlinks denoted by <A>
+   elements. HTML user agents should also allow activation of <LINK>
+   element hyperlinks.
+
+   To activate a link, the user agent obtains a representation of the
+   resource identified in the address of the head anchor. If the
+   representation is another HTML document, navigation may begin again
+   with this new document.
+
+7.3. Simultaneous Presentation of Image Resources
+
+   An HTML user agent may activate hyperlinks indicated by <IMG> and
+   <INPUT> elements concurrently with processing the document; that is,
+   image hyperlinks may be processed without explicit request by the
+   user. Image resources should be embedded in the presentation at the
+   point of the tail anchor, that is the <IMG> or <INPUT> element.
+
+   <LINK> hyperlinks may also be processed without explicit user
+   request; for example, style sheet resources may be processed before
+   or during the processing of the document.
+
+7.4. Fragment Identifiers
+
+   Any characters following a `#' character in a hypertext address
+   constitute a fragment identifier. In particular, an address of the
+   form `#fragment' refers to an anchor in the same document.
+
+   The meaning of fragment identifiers depends on the media type of the
+   representation of the anchor's resource. For `text/html'
+   representations, it refers to the <A> element with a NAME attribute
+   whose value is the same as the fragment identifier.  The matching is
+   case sensitive. The document should have exactly one such element.
+   The user agent should indicate the anchor element, for example by
+   scrolling to and/or highlighting the phrase.
+
+   For example, if the base URI is `http://host/x/y.html' and the user
+   activated the link denoted by the following markup:
+
+   <p> See: <a href="app1.html#bananas">appendix 1</a>
+   for more detail on bananas.
+
+
+
+
+
+Berners-Lee & Connolly      Standards Track                    [Page 38]
+
+RFC 1866            Hypertext Markup Language - 2.0        November 1995
+
+
+   Then the user agent accesses the resource identified by
+   `http://host/x/app1.html'. Assuming the resource is represented using
+   the `text/html' media type, the user agent must locate the <A>
+   element whose NAME attribute is `bananas' and begin navigation there.
+
+7.5. Queries and Indexes
+
+   The <ISINDEX> element represents a set of hyperlinks. The user can
+   choose from the set by providing keywords to the user agent.  The
+   user agent computes the head URI by appending `?' and the keywords to
+   the base URI. The keywords are escaped according to [URL] and joined
+   by `+'. For example, if a document contains:
+
+    <BASE HREF="http://host/index">
+    <ISINDEX>
+
+    and the user provides the keywords `apple' and `berry', then the
+    user agent must access the resource
+    `http://host/index?apple+berry'.
+
+    <FORM> elements with `METHOD=GET' also represent sets of
+    hyperlinks. See 8.2.2, "Query Forms: METHOD=GET" for details.
+
+7.6. Image Maps
+
+   If the ISMAP attribute is present on an <IMG> element, the <IMG>
+   element must be contained in an <A> element with an HREF present.
+   This construct represents a set of hyperlinks. The user can choose
+   from the set by choosing a pixel of the image. The user agent
+   computes the head URI by appending `?' and the x and y coordinates of
+   the pixel to the URI given in the <A> element.  For example, if a
+   document contains:
+
+   <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
+   <head><title>ImageMap Example</title>
+   <BASE HREF="http://host/index"></head>
+   <body>
+   <p> Choose any of these icons:<br>
+   <a href="/cgi-bin/imagemap"><img ismap src="icons.gif"></a>
+
+   and the user chooses the upper-leftmost pixel, the chosen
+   hyperlink is the one with the URI
+   `http://host/cgi-bin/imagemap?0,0'.

+
+8. Forms
+
+   A form is a template for a form data set and an associated
+   method and action URI. A form data set is a sequence of
+   name/value pair fields. The names are specified on the NAME
+   attributes of form input elements, and the values are given
+   initial values by various forms of markup and edited by the
+   user. The resulting form data set is used to access an
+   information service as a function of the action and method.
+
+   Forms elements can be mixed in with document structuring
+   elements. For example, a <PRE> element may contain a <FORM>
+   element, or a <FORM> element may contain lists which contain
+   <INPUT> elements. This gives considerable flexibility in
+   designing the layout of forms.
+
+   Form processing is a level 2 feature.
+
+8.1. Form Elements
+
+8.1.1. Form: FORM
+
+   The <FORM> element contains a sequence of input elements, along
+   with document structuring elements. The attributes are:
+
+    ACTION
+            specifies the action URI for the form. The action URI of
+            a form defaults to the base URI of the document (see 7,
+            "Hyperlinks").
+
+    METHOD
+            selects a method of accessing the action URI. The set of
+            applicable methods is a function of the scheme of the
+            action URI of the form. See 8.2.2, "Query Forms:
+            METHOD=GET" and 8.2.3, "Forms with Side-Effects:
+            METHOD=POST".
+
+    ENCTYPE
+            specifies the media type used to encode the name/value
+            pairs for transport, in case the protocol does not
+            itself impose a format. See 8.2.1, "The form-urlencoded
+            Media Type".
+
+8.1.2. Input Field: INPUT
+
+   The <INPUT> element represents a field for user input. The TYPE
+   attribute discriminates between several variations of fields.
+
+
+
+
+Berners-Lee & Connolly      Standards Track                    [Page 40]
+
+RFC 1866            Hypertext Markup Language - 2.0        November 1995
+
+
+   The <INPUT> element has a number of attributes. The set of applicable
+   attributes depends on the value of the TYPE attribute.
+
+8.1.2.1. Text Field: INPUT TYPE=TEXT
+
+   The default value of the TYPE attribute is `TEXT', indicating a
+   single line text entry field. (Use the <TEXTAREA> element for multi-
+   line text fields.)
+
+   Required attributes are:
+
+    NAME
+            name for the form field corresponding to this element.
+
+    The optional attributes are:
+
+    MAXLENGTH
+            constrains the number of characters that can be entered
+            into a text input field. If the value of MAXLENGTH is
+            greater the the value of the SIZE attribute, the field
+            should scroll appropriately. The default number of
+            characters is unlimited.
+
+    SIZE
+            specifies the amount of display space allocated to this
+            input field according to its type. The default depends
+            on the user agent.
+
+    VALUE
+            The initial value of the field.
+
+    For example:
+
+<p>Street Address: <input name=street><br>
+Postal City code: <input name=city size=16 maxlength=16><br>
+Zip Code: <input name=zip size=10 maxlength=10 value="99999-9999"><br>
+
+8.1.2.2. Password Field: INPUT TYPE=PASSWORD
+
+   An <INPUT> element with `TYPE=PASSWORD' is a text field as above,
+   except that the value is obscured as it is entered. (see also: 10,
+   "Security Considerations").
+
+   For example:
+
+<p>Name: <input name=login> Password: <input type=password name=passwd>

+8.1.2.3. Check Box: INPUT TYPE=CHECKBOX
+
+   An <INPUT> element with `TYPE=CHECKBOX' represents a boolean choice.
+   A set of such elements with the same name represents an n-of-many
+   choice field. Required attributes are:
+
+    NAME
+            symbolic name for the form field corresponding to this
+            element or group of elements.
+
+    VALUE
+            The portion of the value of the field contributed by
+            this element.
+
+    Optional attributes are:
+
+    CHECKED
+            indicates that the initial state is on.
+
+    For example:
+
+  <p>What flavors do you like?
+  <input type=checkbox name=flavor value=vanilla>Vanilla<br>
+  <input type=checkbox name=flavor value=strawberry>Strawberry<br>
+  <input type=checkbox name=flavor value=chocolate checked>Chocolate<br>
+
+8.1.2.4. Radio Button: INPUT TYPE=RADIO
+
+   An <INPUT> element with `TYPE=RADIO' represents a boolean choice. A
+   set of such elements with the same name represents a 1-of-many choice
+   field. The NAME and VALUE attributes are required as for check boxes.
+   Optional attributes are:
+
+    CHECKED
+            indicates that the initial state is on.
+   At all times, exactly one of the radio buttons in a set is checked.
+   If none of the <INPUT> elements of a set of radio buttons specifies
+   `CHECKED', then the user agent must check the first radio button of
+   the set initially.
+
+   For example:
+
+    <p>Which is your favorite?
+    <input type=radio name=flavor value=vanilla>Vanilla<br>
+    <input type=radio name=flavor value=strawberry>Strawberry<br>
+    <input type=radio name=flavor value=chocolate>Chocolate<br>

+
+
+8.1.2.5. Image Pixel: INPUT TYPE=IMAGE
+
+   An <INPUT> element with `TYPE=IMAGE' specifies an image resource to
+   display, and allows input of two form fields: the x and y coordinate
+   of a pixel chosen from the image. The names of the fields are the
+   name of the field with `.x' and `.y' appended.  `TYPE=IMAGE' implies
+   `TYPE=SUBMIT' processing; that is, when a pixel is chosen, the form
+   as a whole is submitted.
+
+   The NAME attribute is required as for other input fields. The SRC
+   attribute is required and the ALIGN is optional as for the <IMG>
+   element (see 5.10, "Image: IMG").
+
+   For example:
+
+    <p>Choose a point on the map:
+    <input type=image name=point src="map.gif">
+
+8.1.2.6. Hidden Field: INPUT TYPE=HIDDEN
+
+   An <INPUT> element with `TYPE=HIDDEN' represents a hidden field.The
+   user does not interact with this field; instead, the VALUE attribute
+   specifies the value of the field. The NAME and VALUE attributes are
+   required.
+
+   For example:
+
+   <input type=hidden name=context value="l2k3j4l2k3j4l2k3j4lk23">
+
+8.1.2.7. Submit Button: INPUT TYPE=SUBMIT
+
+   An <INPUT> element with `TYPE=SUBMIT' represents an input option,
+   typically a button, that instructs the user agent to submit the form.
+   Optional attributes are:
+
+    NAME
+            indicates that this element contributes a form field
+            whose value is given by the VALUE attribute. If the NAME
+            attribute is not present, this element does not
+            contribute a form field.
+
+    VALUE
+            indicates a label for the input (button).
+
+    You may submit this request internally:
+    <input type=submit name=recipient value=internal><br>
+    or to the external world:
+    <input type=submit name=recipient value=world>

+
+
+8.1.2.8. Reset Button: INPUT TYPE=RESET
+
+   An <INPUT> element with `TYPE=RESET' represents an input option,
+   typically a button, that instructs the user agent to reset the form's
+   fields to their initial states. The VALUE attribute, if present,
+   indicates a label for the input (button).
+
+   When you are finished, you may submit this request:
+   <input type=submit><br>
+   You may clear the form and start over at any time: <input type=reset>
+
+8.1.3. Selection: SELECT
+
+   The <SELECT> element constrains the form field to an enumerated list
+   of values. The values are given in <OPTION> elements.  Attributes
+   are:
+
+    MULTIPLE
+            indicates that more than one option may be included in
+            the value.
+
+    NAME
+            specifies the name of the form field.
+
+    SIZE
+            specifies the number of visible items. Select fields of
+            size one are typically pop-down menus, whereas select
+            fields with size greater than one are typically lists.
+
+    For example:
+
+    <SELECT NAME="flavor">
+    <OPTION>Vanilla
+    <OPTION>Strawberry
+    <OPTION value="RumRasin">Rum and Raisin
+    <OPTION selected>Peach and Orange
+    </SELECT>
+
+   The initial state has the first option selected, unless a SELECTED
+   attribute is present on any of the <OPTION> elements.
+
+8.1.3.1. Option: OPTION
+
+   The Option element can only occur within a Select element. It
+   represents one choice, and has the following attributes:
+
+    SELECTED
+            Indicates that this option is initially selected.

+
+RFC 1866            Hypertext Markup Language - 2.0        November 1995
+
+
+    VALUE
+            indicates the value to be returned if this option is
+            chosen. The field value defaults to the content of the
+            <OPTION> element.
+
+   The content of the <OPTION> element is presented to the user to
+   represent the option. It is used as a returned value if the VALUE
+   attribute is not present.
+
+8.1.4. Text Area: TEXTAREA
+
+   The <TEXTAREA> element represents a multi-line text field.
+   Attributes are:
+
+    COLS
+            the number of visible columns to display for the text
+            area, in characters.
+
+    NAME
+            Specifies the name of the form field.
+
+    ROWS
+            The number of visible rows to display for the text area,
+            in characters.
+
+    For example:
+
+    <TEXTAREA NAME="address" ROWS=6 COLS=64>
+    HaL Computer Systems
+    1315 Dell Avenue
+    Campbell, California 95008
+    </TEXTAREA>
+
+   The content of the <TEXTAREA> element is the field's initial value.
+
+   Typically, the ROWS and COLS attributes determine the visible
+   dimension of the field in characters. The field is typically rendered
+   in a fixed-width font. HTML user agents should allow text to extend
+   beyond these limits by scrolling as needed.
+
+8.2. Form Submission
+
+   An HTML user agent begins processing a form by presenting the
+   document with the fields in their initial state. The user is allowed
+   to modify the fields, constrained by the field type etc.  When the
+   user indicates that the form should be submitted (using a submit
+   button or image input), the form data set is processed according to
+   its method, action URI and enctype.
+
+
+
+Berners-Lee & Connolly      Standards Track                    [Page 45]
+
+RFC 1866            Hypertext Markup Language - 2.0        November 1995
+
+
+   When there is only one single-line text input field in a form, the
+   user agent should accept Enter in that field as a request to submit
+   the form.
+
+8.2.1. The form-urlencoded Media Type
+
+   The default encoding for all forms is `application/x-www-form-
+   urlencoded'. A form data set is represented in this media type as
+   follows:
+
+        1. The form field names and values are escaped: space
+        characters are replaced by `+', and then reserved characters
+        are escaped as per [URL]; that is, non-alphanumeric
+        characters are replaced by `%HH', a percent sign and two
+        hexadecimal digits representing the ASCII code of the
+        character. Line breaks, as in multi-line text field values,
+        are represented as CR LF pairs, i.e. `%0D%0A'.
+
+        2. The fields are listed in the order they appear in the
+        document with the name separated from the value by `=' and
+        the pairs separated from each other by `&'. Fields with null
+        values may be omitted. In particular, unselected radio
+        buttons and checkboxes should not appear in the encoded
+        data, but hidden fields with VALUE attributes present
+        should.
+
+            NOTE - The URI from a query form submission can be
+            used in a normal anchor style hyperlink.
+            Unfortunately, the use of the `&' character to
+            separate form fields interacts with its use in SGML
+            attribute values as an entity reference delimiter.
+            For example, the URI `http://host/?x=1&y=2' must be
+            written `<a href="http://host/?x=1&#38;y=2"' or `<a
+            href="http://host/?x=1&amp;y=2">'.
+
+            HTTP server implementors, and in particular, CGI
+            implementors are encouraged to support the use of
+            `;' in place of `&' to save users the trouble of
+            escaping `&' characters this way.
+
+8.2.2. Query Forms: METHOD=GET
+
+   If the processing of a form is idempotent (i.e. it has no lasting
+   observable effect on the state of the world), then the form method
+   should be `GET'. Many database searches have no visible side-effects
+   and make ideal applications of query forms.
+
+
+
+
+
+Berners-Lee & Connolly      Standards Track                    [Page 46]
+
+RFC 1866            Hypertext Markup Language - 2.0        November 1995
+
+
+   To process a form whose action URL is an HTTP URL and whose method is
+   `GET', the user agent starts with the action URI and appends a `?'
+   and the form data set, in `application/x-www-form-urlencoded' format
+   as above. The user agent then traverses the link to this URI just as
+   if it were an anchor (see 7.2, "Activation of Hyperlinks").
+
+      NOTE - The URL encoding may result in very long URIs, which cause
+      some historical HTTP server implementations to exhibit defective
+      behavior. As a result, some HTML forms are written using
+      `METHOD=POST' even though the form submission has no side-effects.
+
+8.2.3. Forms with Side-Effects: METHOD=POST
+
+   If the service associated with the processing of a form has side
+   effects (for example, modification of a database or subscription to a
+   service), the method should be `POST'.
+
+   To process a form whose action URL is an HTTP URL and whose method is
+   `POST', the user agent conducts an HTTP POST transaction using the
+   action URI, and a message body of type `application/x-www-form-
+   urlencoded' format as above. The user agent should display the
+   response from the HTTP POST interaction just as it would display the
+   response from an HTTP GET above.
+
+8.2.4. Example Form Submission: Questionnaire Form
+
+   Consider the following document:
+
+    <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
+    <title>Sample of HTML Form Submission</title>
+    <H1>Sample Questionnaire</H1>

+9.6. Sample SGML Open Entity Catalog for HTML
+
+   The SGML standard describes an "entity manager" as the portion or
+   component of an SGML system that maps SGML entities into the actual
+   storage model (e.g., the file system). The standard itself does not

+RFC 1866            Hypertext Markup Language - 2.0        November 1995
+
+
+   define a particular mapping methodology or notation.
+
+   To assist the interoperability among various SGML tools and systems,
+   the SGML Open consortium has passed a technical resolution that
+   defines a format for an application-independent entity catalog that
+   maps external identifiers and/or entity names to file names.
+
+   Each entry in the catalog associates a storage object identifier
+   (such as a file name) with information about the external entity that
+   appears in the SGML document. In addition to entries that associate
+   public identifiers, a catalog entry can associate an entity name with
+   a storage object identifier. For example, the following are possible
+   catalog entries:

+10. Security Considerations
+
+   Anchors, embedded images, and all other elements which contain URIs
+   as parameters may cause the URI to be dereferenced in response to
+   user input. In this case, the security considerations of [URL] apply.
+
+   The widely deployed methods for submitting forms requests -- HTTP and
+   SMTP -- provide little assurance of confidentiality.  Information
+   providers who request sensitive information via forms -- especially
+   by way of the `PASSWORD' type input field (see 8.1.2, "Input Field:
+   INPUT") -- should be aware and make their users aware of the lack of
+   confidentiality.

+12. Acknowledgments
+
+   The HTML document type was designed by Tim Berners-Lee at CERN as
+   part of the 1990 World Wide Web project. In 1992, Dan Connolly wrote
+   the HTML Document Type Definition (DTD) and a brief HTML
+   specification.
+
+   Since 1993, a wide variety of Internet participants have contributed
+   to the evolution of HTML, which has included the addition of in-line
+   images introduced by the NCSA Mosaic software for WWW. Dave Raggett
+   played an important role in deriving the forms material from the
+   HTML+ specification.
+
+   Dan Connolly and Karen Olson Muldrow rewrote the HTML Specification
+   in 1994. The document was then edited by the HTML working group as a
+   whole, with updates being made by Eric Schieler, Mike Knezovich, and
+   Eric W. Sink at Spyglass, Inc.  Finally, Roy Fielding restructured
+   the entire draft into its current form.
+
+   Special thanks to the many active participants in the HTML working
+   group, too numerous to list individually, without whom there would be
+   no standards process and no standard. That this document approaches
+   its objective of carefully converging a description of current
+   practice and formalization of HTML's relationship to SGML is a
+   tribute to their effort.

+14. Proposed Entities
+
+   The HTML DTD references the "Added Latin 1" entity set, which only
+   supplies named entities for a subset of the non-ASCII characters in
+   [ISO-8859-1], namely the accented characters. The following entities
+   should be supported so that all ISO 8859-1 characters may only be
+   referenced symbolically. The names for these entities are taken from
+   the appendixes of [SGML].
