Taylor +Request for Comments: 4735 Nortel +Category: Standards Track October 2006 + + + Example Media Types for Use in Documentation + +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. + +Copyright Notice + + Copyright (C) The Internet Society (2006). + +Abstract + + This document is registration for the 'example' media type and + 'example' subtypes within the standards tree. The 'example/*' and + '*/example' media types are defined for documentation purposes only. + +1. Introduction + + From time to time, documents created by the IETF or by other + standards bodies show examples involving the use of media types, + where the actual media type is not relevant. It would be useful in + such cases to be able to show a media type whose illustrative role in + the example is clear. In the worst case, this can be useful to debug + implementations where the designer mistook the example for a + requirement of the protocol concerned. + + To meet this need, this document registers the following media types: + + o the 'example' media type; + + o the 'application/example', 'audio/example', 'image/example', + 'message/example', 'model/example', 'multipart/example', + 'text/example', and 'video/example' media subtypes. + + It is suggested that compilers of illustrative examples involving + media types in trees other than the standards tree might also + incorporate the string "example" into their hypothetical media types. + + + + + +Taylor Standards Track [Page 1] + +RFC 4735 Example Media Types October 2006 + + +2. Terminology + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in [RFC2119]. + +3. Registration of the 'example' Media Type + + This section registers the 'example' media type in accordance with + the requirements of RFC 4288. + + Type name: example. + + Subtype name: any subtype may be used with the 'example' type. + However, IANA MUST NOT register any subtypes for the 'example' media + type. + + + Required parameters: as invented by the user. + + Optional parameters: as invented by the user. + + Encoding considerations: as invented by the user. + + Security considerations: The 'example' media type is defined for use + in documentation only. It MUST NOT be implemented. Its appearance + in real code could lead to unpredictable results and therefore open + up security holes. + + Interoperability considerations: Any attempt to negotiate or send the + 'example' media type is bound to lead to interoperability problems. + + Published specification: this document. + + Applications that use this media type: as invented by the user. + + Additional information: + Magic number(s): not applicable. + File extension(s): not applicable. + Macintosh file type code(s): not applicable. + + Person & email address to contact for further information: + ietf-types@iana.org. + + Intended usage: LIMITED USE. + + + + + + +Taylor Standards Track [Page 2] + +RFC 4735 Example Media Types October 2006 + + + Restrictions on usage: This type is intended only for use in + documents providing examples involving specification of some media + type, where the actual media type used is irrelevant. + + Author: Internet Engineering Task Force + + Change controller: Internet Engineering Task Force + +4. Registration of the 'application/example', 'audio/example', + 'image/example', 'message/example', 'model/example', + 'multipart/example', 'text/example', and 'video/example' Subtypes + + This section registers 'example' media subtypes in accordance with + the requirements of RFC 4288. + + Type name: 'application', 'audio', 'image', 'message', 'model', + 'multipart', 'text', and 'video'. + + Subtype name: 'example'. + + Required parameters: those required by the type and any others as + invented by the user. + + Optional parameters: those offered by the type and any others as + invented by the user. + + Encoding considerations: as invented by the user. + + Security considerations: The 'example' media subtypes are defined + for use in documentation only.

Security Considerations + + The 'example' media type and subtypes are defined for use in + documentation only. They MUST NOT be implemented. Any attempt to + implement them in real code could lead to unpredictable results and + thus potentially open up security holes. + +6. IANA Considerations + + This document specifies and registers the 'example' media type and + the 'application/example', 'audio/example', 'image/example', + 'message/example', 'model/example', 'multipart/example', + 'text/example', and 'video/example' subtypes. + +7. Acknowledgements + + This document sprang from Magnus Westerland's expression of need and + Rod Walsh's support and suggestions for generalization. Warnings + against implementation in the Security Considerations and + Interoperability Considerations sections and the 'multipart/example' + subtype were added at John Klensin's suggestion. Some editing + touchups and strengthening of the language in the Security + Considerations section were done in response to the Gen-ART reviewer, + Sharon Chisholm. + +8.
