====== 5.1.4 Reuse ======

[[public:00-sip-ra:05-general-requirements-on-proposals:05-1-requirements:start|Return to Requirements]]

Reuse promotes compatibility with the existing standards ecosystem and avoids duplicating established models and capabilities.

===== Notes for Editors =====

The requirement identifier and short title link to the authoritative requirement record in Annex C.

The Statement displayed in this section is transcluded from its Annex C requirement page and is not an independently maintained copy.

Make changes to the Statement or its Requirement Level on its Annex C requirement page.

The qualification “applicable” avoids requiring use of a standard that does not satisfy the architectural need. The term “equivalent capabilities” provides a more objective basis for evaluation than “similar functionality.”

When no applicable existing standard provides the required capability, the Submission may define a new model but should identify the standards considered and explain the unmet need.

GPR-007 establishes the general obligation to reuse applicable standards.
