Hi,

Section 5.1 of RFC 3680 (reg event package) says:

"Other elements from different namespaces MAY be present for the
purposes of extensibility; elements or attributes from unknown
namespaces MUST be ignored."

However, there is no policy regarding whether the definition of these "other namespaces" needs to be done in IETF - only that they must be ignored if not supported.

3GPP has been discussing a couple of IMS specific cases, in which such extension elements/attributes could be used as solution (no decissions have been made yet), so the question is whether it would require IETF work.

Regards,

Christer
