Agreed.  But I don't think we need to.  Legacy INFO is already deployed.  Subscribe/Notify is already deployed.  UPDATE is already deployed. MESSAGE is already deployed.  None of them use a CID for the body part that is germane to their method's context, AFAIK.  It is up to the piggy-backer uses that want to add other body-parts to use CID for their parts.  For example, if you wanted to add a body part for geo-loc to a Notify message that was sent for a presence package, the Geolocation header would contain a CID, not the Event header.

This "problem" already exists for current SIP messages, and it's up to the new extensions that add body-parts to solve it in a backward-compatible way for all message methods.  We don't need to solve it specifically for INFO.
