 +====== 5.1.5 Changes to Existing Specifications ======
  
 +[[public:00-sip-ra:05-general-requirements-on-proposals:05-1-requirements:start|Return to Requirements]]
 +
 +A Submission may identify changes or extensions to existing OMG specifications that would be required for its adoption. GPR-008 governs how to identify, justify, and specify those changes or extensions.
 +
 +===== Requirement =====

 +^ Requirement ^ Level ^ Statement ^
 +| [[public:00-sip-ra:99-annexes:annex-c-requirements:gpr-008-required-changes-and-extensions-to-existing-omg-specifications|GPR-008 — Required Changes and Extensions to Existing OMG Specifications]] | Mandatory when applicable | {{section>public:00-sip-ra:99-annexes:annex-c-requirements:gpr-008-required-changes-and-extensions-to-existing-omg-specifications#Statement&noheader&nofooter&noeditbtn}} |
 +
 +OMG favors Submissions that are upwardly compatible with existing standards and that minimize changes and extensions to existing specifications.
 +
 +===== 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.
 +
 +GPR-008 is mandatory when adoption of the Submission depends on changing or extending an existing OMG specification.
 +
 +The OMG preference for upward compatibility and minimal change is an evaluation consideration rather than a separate normative requirement because it does not use ''SHALL'' or ''SHOULD''.
 +
 +[[public:00-sip-ra:99-annexes:annex-c-requirements:sip-026-preservation-of-existing-omg-specifications|SIP-026 — Preservation of Existing OMG Specifications]] prohibits the Submission from replacing, superseding, or modifying existing OMG specifications. Consequently, a proposed change governed by GPR-008 must also comply with SIP-026.
 +
 +A proposed extension must remain consistent with the scope restrictions of this RFP and must not redefine or duplicate capabilities governed by:

 +  * [[public:00-sip-ra:99-annexes:annex-c-requirements:sip-034-preservation-of-existing-transport-and-exchange-constructs|SIP-034 — Preservation of Existing Transport and Exchange Constructs]]
