Introduction + + Over the last few years, the RFC Editor has worked with the Internet + community to develop specifications for changes in the format of + RFCs. An outline of the resulting specifications was published as + [RFC6949] in May 2013. Since then, a Design Team has been working + with the RFC Editor to flesh out those specifications. One aspect of + the changes is to allow line drawings in RFCs; [RFC6949] says + + Graphics may include ASCII art and a more complex form to be + defined, such as SVG line art [SVG]. Color and grayscale will not + be accepted. RFCs must correctly display in monochromatic black- + and-white to allow for monochrome displays, black-and-white + printing, and support for visual disabilities. + + SVG (Scalable Vector Graphics) has been developed by W3C, the World + Wide Web Consortium; its current standard is SVG 1.1 Full + [W3C.REC-SVG11-20110816]. This document defines SVG 1.2 RFC, an SVG + profile (i.e., a subset of SVG) that is suitable for RFC line + drawings. + + Note that in RFCs, the text provides normative descriptions of + protocols, systems, etc. Diagrams may be used to help explain + concepts more clearly, but they provide supporting details and should + not be considered to be complete specifications in themselves. + + + + + +Brownlee Informational [Page 2] + +RFC 7996 SVG Drawings for RFCs: SVG 1.2 RFC December 2016 + + + The details (particularly any vocabularies) described in this + document are expected to change based on experience gained in + implementing the new publication toolsets. Revised documents will be + published capturing those changes as the toolsets are completed. + Other implementers must not expect those changes to remain backwards- + compatible with the details described in this document. + +2. SVG 1.2 RFC: An SVG Profile for RFCs + + As a starting point for SVG 1.2 RFC, the Design Team decided to use + SVG Tiny 1.2 (also referred to as "SVG 1.2 Tiny") + [W3C.REC-SVGTiny12-20081222]. SVG 1.2 Tiny is an SVG subset intended + to be implemented on small, mobile devices such as cell phones and + smartphones. That should allow RFCs to be rendered well on such + devices, especially those that have small screens. However, RFCs are + self-contained documents that do not change once they are published. + The use of SVG drawings in RFCs is intended to allow authors to + create drawings that are simple to produce and are easier to + understand than our traditional "ASCII art" ones. In short, we are + also trying to improve access to the content in RFCs, so SVG drawings + need to be kept as simple as possible. + + Appendix A (below) provides a complete RELAX NG Compact (RNC) schema + [RNG-HOME] for SVG 1.2 RFC. It is derived from the SVG 1.2 schema, + and is the formal definition of SVG 1.2 RFC. The remainder of this + section gives a simplified -- i.e., easier to read and understand -- + overview of SVG 1.2 RFC. + + SVG can provide a complete User Interface, but within RFCs, all we + need are simple diagrams that do not change once the RFC is + published. Therefore, SVG 1.2 RFC does not allow anything from the + following sections in SVG Tiny 1.2 [W3C.REC-SVGTiny12-20081222]: + + 12 Multimedia + 13 Interactivity + 15 Scripting + 16 Animation + 18 Metadata + 19 Extensibility + + Note that SVG Tiny 1.2 elements may have many properties or + attributes that are needed to support aspects of the above sections. + Those are not allowed in SVG 1.2 RFC. + + + + + + + + +Brownlee Informational [Page 3] + +RFC 7996 SVG Drawings for RFCs: SVG 1.2 RFC December 2016 + + + We now consider these other sections in SVG Tiny 1.2 + [W3C.REC-SVGTiny12-20081222]: + + 9 Basic Shapes + + 10 Text + Everything in this section is allowed in SVG 1.2 RFC. + + 11 Painting: Filling, Stroking, Colors and Paint Servers + Anything relating to 'color' is not allowed in SVG 1.2 RFC; + everything else is allowed. This is a requirement documented in + [RFC6949]. + + 14 Linking + SVG Tiny 1.2 allows Internationalized Resource Identifiers + (IRIs) in references. In SVG 1.2 RFC, such links must be ASCII + only. That should not cause problems, since one can just use + the URI form of any IRI. Authors should try to use links only + to URIs that are long-term stable. + + 17 Fonts + SVG 1.2 RFC only allows 'serif', 'sans-serif', and 'monospace' + generic font families from the WebFonts facility, described in + Section 15 ("Fonts") of the W3C Cascading Style Sheets (CSS) 2.1 + document [W3C.REC-CSS2-20110607]. In particular, the SVG 'font' + element is not allowed. + +2.1. Elements, Properties, and Attributes Allowed in SVG 1.2 RFC + + This section discusses elements, properties, and attributes selected + for SVG 1.2 RFC from [W3C.REC-SVGTiny12-20081222]. + + In the list below, elements and properties are listed on the + left, and their allowed values are given in parentheses on the + right. + + <color> is the list of allowed colors, a black-and-white + subset of the SVG color names. + + <style> is a set of CSS attributes that are commonly used (by SVG + drawing applications). They are not part of SVG Tiny 1.2 + but are included here for compatibility. Note that + + - There is no guarantee that any renderer will implement + all the CSS attributes a drawing application may use. + + - Authors will need to consider the compatibility of their + drawings with rendering devices. + + + +Brownlee Informational [Page 4] + +RFC 7996 SVG Drawings for RFCs: SVG 1.2 RFC December 2016 + + + Elements: + + svg (version=1.2, baseProfile=tiny, width, viewBox, + preserveAspectRatio, snapshotTime, height, + id, role) + g (label, class, id, role, fill, <style>, transform) + defs (id, role, fill) + title (id, role) + desc (id, role) + a (id, role, fill, transform) + use (x, y, href, xlink:href, id, role, + fill, transform) + + rect (x, y, width, height, rx, ry, stroke-miterlimit, + id, role, fill, <style>, transform) + circle (cx, cy, r, id, role, fill, <style>, transform) + ellipse (cx, cy, rx, ry, id, role, + fill, <style>, transform) + line (x1, y1, x2, y2, id, role, fill, transform) + polyline (points, id, role, fill, transform) + polygon (points, id, role, fill, <style>, transform) + text (x, y, rotate, space, id, role, fill, <style>, + transform) + tspan (x, y, id, role, fill) + textArea (x, y, width, height, auto, id, role, fill, + transform) + tbreak (id, role) + + solidColor (id, role, fill) + linearGradient (gradientUnits, x1, y1, x2, y2, id, role, fill) + radialGradient (gradientUnits, cx, cy, r, id, role, fill) + stop (id, role, fill) + path (d, pathLength, stroke-miterlimit, + id, role, fill, <style>, transform) + + Properties: (most allow "inherit" as a value) + + <style> (font-family, font-weight, font-style, + font-variant, direction, unicode-bidi, + text-anchor, fill, fill-rule) + + <color> (black, white, #000000, #ffffff, #FFFFFF) + + stroke (<color>, none, currentColor) + stroke-width + stroke-linecap (butt, round, square) + stroke-linejoin (miter, round, bevel) + stroke-miterlimit + + + +Brownlee Informational [Page 5] + +RFC 7996 SVG Drawings for RFCs: SVG 1.2 RFC December 2016 + + + stroke-dasharray + stroke-dashoffset + stroke-opacity + vector-effect (non-scaling-stroke, none) + viewport-fill (none, currentColor) + viewport-fill-opacity + + display (inline, block, list-item, run-in, compact, + marker, table, inline-table, table-row-group, + table-header-group, table-footer-group, + table-row, table-column-group, + table-column, table-cell, table-caption, + none) + visibility (visible, hidden, collapse) + color-rendering (auto, optimizeSpeed, optimizeQuality) + shape-rendering (auto, optimizeSpeed, crispEdges, + geometricPrecision) + text-rendering (auto, optimizeSpeed, optimizeLegibility, + geometricPrecision) + buffered-rendering (auto, dynamic, static) + + opacity + solid-opacity + solid-color (currentColor, <color>) + color (currentColor, <color>) + stop-color (currentColor, <color>) + stop-opacity + + line-increment (auto) + text-align (start, end, center) + display-align (auto, before, center, after) + + font-size + font-family (serif, sans-serif, monospace) + font-weight (normal, bold, bolder, lighter) + font-style (normal, italic, oblique) + font-variant (normal, small-caps) + direction (ltr, rtl) + unicode-bidi (normal, embed, bidi-override) + text-anchor (start, middle, end) + fill (none, <color>) + fill-rule (nonzero, evenodd) + fill-opacity + + + + + + + + +Brownlee Informational [Page 6] + +RFC 7996 SVG Drawings for RFCs: SVG 1.2 RFC December 2016 + + +3. How to Create SVG Drawings + + Many drawing packages can be used to create SVG drawings -- for + example, Open Source packages Inkscape and Dia. Be aware that such + packages may use SVG elements or attributes that are not allowed in + SVG 1.2 RFC. + + o For example, the 'marker' attribute is often used to place symbols + such as arrowheads on lines, but 'marker' is not allowed in + SVG 1.2 Tiny or SVG 1.2 RFC. In such cases, one has to draw the + arrowhead in another, simpler way. + + o SVG clip paths are used to define a shape; objects outside that + shape become invisible. The 'clipPath' element is not allowed in + SVG 1.2 Tiny or SVG 1.2 RFC. + + Diagrams produced with these packages may contain elements, their + attributes or properties, or values of attributes or properties that + are not allowed in SVG 1.2 RFC. We will need to provide a tool to + either (1) strip out anything that is not allowed in SVG 1.2 RFC or + (2) replace disallowed values (e.g., replace 'Sans' with 'sans-serif' + as an allowed value for 'font-family'). Experience with a simple + test version of a tool for this has shown that such deletion and + replacement can be effective for making SVG files from drawing + packages conform to SVG 1.2 RFC, without visibly changing the + diagrams they produce. + + The tool described above can also be used by authors simply to check + that their diagrams conform to SVG 1.2 RFC. To help with this, if + visible changes do occur, the tool should produce a list of + non-allowed keywords and the context in which they were found. + + To include a diagram in an RFC, the xml2rfc (v3) tool will need to + provide a way to include SVG drawings in Internet-Drafts, as + described in Section 2.5 of [RFC7991]. + +4. Accessibility Considerations + + One of the long-term goals for RFCs is to make them more accessible, + e.g., to sight-impaired readers. For diagrams, it would be useful + for authors to provide alternative forms of the diagram, so that + voice-reading software could be used to "talk through" the diagram. + Simply reading the SVG code for a complex diagram seems unlikely + to work. + + + + + + + +Brownlee Informational [Page 7] + +RFC 7996 SVG Drawings for RFCs: SVG 1.2 RFC December 2016 + + + SVG 1.2 RFC allows SVG's 'title' and 'desc' elements. 'title' + provides a brief text caption for an SVG object (much like a figure + caption), and 'desc' provides a longer text description of what the + object actually represents. As well, the SVG 'role' attribute can be + used to indicate to a browser how an SVG object is to be interpreted. + Good suggestions on how to use these elements are given in + [SVG-ACCESS-TIPS]. + + ARIA is a W3C Recommendation for using SVG to create (as the name + "ARIA" indicates) "Accessible Rich Internet Applications". A helpful + introduction to ARIA is provided by [SVG-ARIA-PRIMER], while + [SVG-USING-ARIA] gives examples of how to use ARIA to enhance SVG + accessibility. + +5. Examples of Diagrams Common in RFCs + + Another way to create SVG drawings is to write programs to draw them. + For example, using Python and its svgwrite module is a pleasant + environment (for those who like writing code); this section presents + a few examples of diagrams created in this way. Note that they are + merely examples of typical diagrams from RFCs. + + The SVG diagrams for this section, along with an HTML version of this + document that includes the SVG diagrams, can be seen at + [NB-SVG-1.2-RFC]. + +5.1.
