# Introduction # Introduction
This document sets policy for the inclusion of SVGs (Scalable Vector Graphics) in the definitive versions of RFCs and relevant publication formats. It contains policy req uirements taken from {{RFC7996}} and removes all requirements related to using a spec ific SVG profile or specific implementation code. This document defines policy for the inclusion of Scalable Vector Graphics (SVGs) in the definitive versions of RFCs and relevant publication formats defined in {{RFC9720 }}. It contains policy requirements taken from {{RFC7996}} but removes all requiremen ts related to using a specific SVG profile or implementation code.
SVG has been developed by W3C, the World Wide Web Consortium {{SVG}}. SVG has been developed by the World Wide Web Consortium (W3C); see {{SVG}}.
The RFC Publication Center (RPC) is responsible for making SVG tooling and implementa tion decisions. They may want to use the content of {{RFC7996}} as a starting point f or those decisions, but they are not bound by {{RFC7996}} and they may change element s of the implementation as needed to support the RFC authoring community as long as t hose changes are aligned with the policy requirements in this document. The RFC Production Center (RPC) is responsible for making decisions about SVG tooling and implementation. The RPC may use the content of {{RFC7996}} as a starting point f or those decisions, but they are not bound by {{RFC7996}}. In addition, the RPC may c hange 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.
# Policy Requirements # Policy Requirements
SVG tooling and implementation decisions are made or overseen by the RPC, and must ad here to the policy requirements in this document. Decisions about SVG tooling and implementation are made by the RPC and must adhere to the policy requirements in this document:
* SVGs may be included in RFCs to help explain a concept more clearly, but should not be the only representation of that concept. A good faith effort should be made to as sure that descriptions of concepts - which might include protocols, formats, or syste m architectures - are fully represented in the text of the RFC. At minimum, SVGs shou ld be consistent with the text. * SVGs may be included in RFCs to help explain a concept more clearly, but they shoul d not be the only representation of that concept. A good-faith effort should be made to ensure that descriptions of concepts -- which might include protocols, formats, or system architectures -- are fully represented in the text of the RFC. At minimum, SV Gs should be consistent with the descriptions in the text of the RFC.
* SVGs must not include animation or interactive features. SVGs should include only l imited reactive design elements (scaling, dark/light mode, and perhaps minor adjustme nts to allow for variations in display technology). The intent of this is to ensure t hat the diagram's meaning is not altered. * SVGs must not include animation or interactive features.

The intent of this is to ensure t hat the diagram's meaning is not altered.
* Images and diagrams in RFCs should be successfully rendered and understood by the w idest audience possible. To that end, the RPC may prohibit the use of SVG features th at are known to lack support on common devices, that do not render on small or low-re solution screens, or that could make diagrams less comprehensible for any significant readership.
