If a method was defined in an RFC, it would not be "custom"! However, there are conventions for "custom", "private", or "extension" identifiers that are used in many IETF protocols: If you want to define an identifier for your own experimental use, start it with "X", then a word that is your project's name, your company's name, or even your own name, to provide some "scoping" for the extension, such as "NORTEL", and then another word which identifies the extension. This gives results like: X-NORTEL-RULETEST1 sip:[email protected]:5060 SIP/2.0 CSeq: 1 RULETEST1 If your extension becomes popular enough that multiple projects use it in a consistent way, change the name to remove the project-name part: X-RULETEST1 sip:[email protected]:5060 SIP/2.0 CSeq: 1 RULETEST1 This convention can be applied to other element names in protocols.
