Current Proposal
Move forward with media tag document, but its not a 3gpp dependency
Move forward with P-Asserted-Service (for usage for things in sipping-service-id)
3gpp registers a media feature tag for ‘app-ref’ in vendor space and it contains a URN, JUST for dispatch ala RFC3841
Service-ID sipping draft have lots of words on the perils of relying entirely on the service ID for endpoint and proxy dispatch
3gpp utilize caller prefs for proxy dispatch to service ID, but not depend on it as described in sipping service ID draft
