1. 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.

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. Packet Layout Diagrams
Example: Figure 3 from [RFC793].
5.2. Sequence Diagrams (1)
Example: Figure 6 from [ExpTrustedProxy].
5.3. Sequence Diagrams (2)
Example: Figure 3 from [RFC4321].
6. Security Considerations
This document does not introduce any security considerations on
its own.

Appendix A. RELAX NG Compact (RNC) Schema for SVG 1.2 RFC
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.
jing -c SVG-1.2-RFC.rnc diagram.svg
The RNC schema included below is available on the RFC Editor website
<https://www.rfc-editor.org/materials/format/SVG-1.2-RFC.rnc>. The
website is considered definitive should there be any discrepancies.
