1. Introduction
Over the last two 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 detail, and should
not be considered to be complete specifications in themselves.

Internet-Draft SVG Drawings for RFCs: SVG 1.2 RFC January 2016
The details (particularly any vocabularies) described in this
document are expected to change based on experience gained in
implementing the RFC production center's toolset. Revised documents
will be published capturing those changes as the toolset is
completed. Other implementors 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 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
cellphones 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
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.
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 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.
Considering the other sections in SVG Tiny 1.2
[W3C.REC-SVGTiny12-20081222]:
9 Basic Shapes
10 Text
Everything in these sections is allowed in SVG 1.2 RFC.
11 Painting: Filling, Stroking, Colors and Paint Servers
Brownlee & IAB Expires July 9, 2016 [Page 3]
Internet-Draft SVG Drawings for RFCs: SVG 1.2 RFC January 2016
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 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
CSS 2.1, [W3C.REC-CSS2-20110607], section 15, Fonts. In
particular, the SVG 'font' element is not allowed.
2.1. Elements, properties and attributes allowed in SVG 1.2 RFC
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.
Elements:

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.
-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.
-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.
Brownlee & IAB Expires July 9, 2016 [Page 6]
Internet-Draft SVG Drawings for RFCs: SVG 1.2 RFC January 2016
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
strip out anything that is not allowed in SVG 1.2 RFC, or to replace
disallowed values, e.g., 'sans-serif' for 'Sans' as values 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.
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).
To include a diagram into an RFC, the xml2rfc (v3) tool will need to
provide a way to include SVG drawings in Internet Drafts, as
described in [XML2RFCv3] sections 2.5 and 2.67.
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.
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 '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. Meta-language for diagrams common in RFCs
This section presents a few examples of possible meta-languages which
could be used to create the kinds of diagrams that are most common in
RFCs. Note that they are merely examples, they do not imply that
these particular experimental languages might be more widely
implemented or used. Instead, they seem to show that designing meta-
languages simple enough to serve as audible representations of
complex diagrams is difficult indeed!
The SVG diagrams produced from the following examples can be seen at
[This-I-D-with-SVG-included] along with an html version of this draft
that includes the SVG diagrams.
5.1. Packet Layout Diagrams
Example: Figure 3 from [RFC0793].
In these examples the first line specifies the generated SVG
filename. The scale factor determines the size of the SVG drawing;
it needs to be set so that the drawing fits nicely into the final
document.
'packet;' starts the packet description; it's followed by a
description of the fields in each row.

5.2. Sequence Diagrams (1)
Example: Figure 6 from [ExpTrustedProxy].
In this example, columns are vertical lines with a text header above
them. There are three columns, and columns 1 and 2 are spaced 250
pixels apart.
The rest of the file describes objects to be drawn; most of them are
plines (polylines) from one column to another, but object 3 only
extends across to 0.3 of the distance between columns 1 and 2.

5.3. Sequence Diagrams (2)
Example: Figure 3 from [RFC4321].
This example uses (x,y) coordinates to specify points in in plines.
For these, the x units are columns and the y units are lines
(positive means 'down the diagram').
both x and y may be absolute, e.g. 4.3, or relative, e.g. +1.5).
For the first point of a pline, relative means 'relative to the
starting point of the previous pline,' for other points in a pline it
means 'relative to the last point.'
Note that column 1 is drawn in white, i.e. nothing is drawn for it.
It's simply used to make a blank area where objects 8 and 9 can place
text. For both those objects a pline is used to specify the text's
position.
Last, the metalanguage allows simple macros, introduced by 'define
foo = '. These make it easier to re-use definitions, for example of
line types.

Section 3: added comment about changes to xml2rfc required to
include SVG diagrams.
Section 4: Added reference to svg-aria-primer.
version -07, 3 Jul 14:
Expanded text about Accessibility in 'how to create SVG drawings'
section into 'Accessibility Considerations section. Added two SVG
Accessibility references to support that.

Internet-Draft SVG Drawings for RFCs: SVG 1.2 RFC January 2016
version -06, 26 Jun 14:
Remove trailing / from URL in section 4; the html version on
tools.ietf.org/html assumed the next word was part of that URL.
version -05, 25 Jun 14:
Improved section on 'how to create SVG drawings' By adding some
text about which elements aren't allowed in SVG 1.2 RFC.
Added more text describing the tool for checking, stripping out or
replacing incompatible elements and attributes from an SVG file.
version -04, 30 Apr 14:
Fixed typos, used full references for two of the w3c refs - each
had an author name using UTF8 characters.
Moved the Elements and Attributes appendix up earlier to make it
sub-section 2.1.
Disclaimer added to the Meta-languages section.
version -03, 14 Apr 14:
Added two more example diagrams; a simple packet layout, and a
diagram that uses lots of diagonal lines.
version -02, 12 Feb 14:
Added metalanguage example to make time-sequence drawings.
version -01, 11 Feb 14:
Allow links to 'long-term stable URIs'
Link URIs must be ASCII only
Need for tools to check SVG 1.2 RFC compatibility and to strip
'unnecessary' attributes explicitly stated.
Statement that drawings can't be normative removed; Postscript-
only RFCs already exist.
Added most attributes and elements to the Appendix.
version -00, 29 Jan 14:
Initial version, using content from Nevil's
emails to the Design Team.

The following rnc schema can be used to check whether an svg file
conforms to SVG 1.2 RFC. For example, if this schema were contained
in a file called SVG-1.2-RFC.rnc, the following command will test
whether svg file diagram.svg is a conformant SVG 1.2 RFC drawing.
