It contains policy requirements taken from <xref target="RFC7996"/> and but removes all requirements related to using a specific SVG profile or specific implementation code.</t>
      <t>SVG has been developed by W3C, the World Wide Web Consortium (W3C); see <xref target="SVG"/>.</t>
      <t>The RFC Publication Production Center (RPC) is responsible for making decisions about SVG tooling and implementation decisions. They implementation. The RPC may want to use the content of <xref target="RFC7996"/> as a starting point for those decisions, but they are not bound by <xref target="RFC7996"/> and they target="RFC7996"/>. In addition, the RPC may change elements of the implementation as needed to support the RFC authoring community as long as those changes are aligned with the policy requirements in this document.</t>

      <t>SVG
      <t>Decisions about SVG tooling and implementation decisions are made or overseen by the RPC, RPC and must adhere to the policy requirements in this document.</t> document:</t>
      <ul spacing="normal">
        <li>
          <t>SVGs may be included in RFCs to help explain a concept more clearly, but they should not be the only representation of that concept. A good faith good-faith effort should be made to assure ensure that descriptions of concepts - -- which might include protocols, formats, or system architectures - -- are fully represented in the text of the RFC. At minimum, SVGs should be consistent with the text.</t> descriptions in the text of the RFC.</t>
        </li>
        <li>
          <t>SVGs must not include animation or interactive features. SVGs should include only limited reactive design elements (scaling, dark/light mode, and perhaps minor adjustments to allow for variations in display technology). The intent of this is to ensure that the diagram's meaning is not altered.</t>
        </li>
        <li>
          <t>Images and diagrams in RFCs should be successfully rendered and understood by the widest audience possible. To that end, the RPC may prohibit the use of SVG features that are known to lack support on common devices, that do not render on small or low-resolution screens, or that could make diagrams less comprehensible for any significant readership. This includes: In particular:
          </t>
          <ul spacing="normal">
            <li>
              <t>SVGs must not contain pointers to external resources.</t>
            </li>
            <li>
              <t>SVGs must not contain executable script.</t>
            </li>
            <li>
              <t>SVGs should be as accessible as possible to people with visual disabilities, including those who have color blindness, those who need to scale or change fonts, and those who use screen reading screen-reading software. The RPC will refer to the W3C Accessibility Guidelines <xref target="WAI"/> when making decisions regarding accessibility.</t>
            </li>
          </ul>
        </li>
        <li>
          <t>Authors may include multiple versions of images or diagrams in rfcxml. RFCXML <xref target="RFC9720"/>.  Publication formats should present the versions best suited to each format.  In many cases, that will be an SVG.</t>
        </li>
        <li>
          <t>SVG vocabulary and implementation may change over time. Changes are not required to remain backwards-compatible, backwards compatible, although maintaining compatibility where possible is encouraged.</t>
        </li>
      </ul>
      <t>The RPC is authorized to place constraints on SVG usage in RFCs for both technical and editorial reasons
in order to ensure that published RFCs meet the above policy
and to provide consistency across the RFC series. Series.
The RPC must document the acceptable usage of SVGs, and all changes to decisions about SVG tooling or and implementation decisions must be widely communicated to the RFC author community using mailing lists or other means.</t>
    </section>
    <section anchor="implementation-guidance">
      <name>Implementation Guidance</name>
      <t>The RPC is expected to solicit community input before making decisions and to publicly explain their reasoning.</t>
      <t>Documentation produced by the RPC should describe what the technical and editorial constraints that apply to SVGs
and provide RFC authors with guidance on how to produce diagrams that meet these those constraints.</t>
      <t>The RPC's implementation should strive to allow SVGs produced by widely used drawing tools.
Where possible, implementation decisions should focus on specifying what is disallowed, disallowed rather than attempting to specify exactly what is allowed.</t>
      <t>The RPC should periodically review and revise their practices.</t>
