Re: [sipcore] Proposal: Call for adoption & WGLC: draft-roach-sipcore-priority-00

[as an individual]

I would *really* like to keep protocol semantics out of the IANA 
registry. The referenced RFC (3261 in this case) is supposed to define 
the semantics for the Priority values.

In particular, there isn't any clear indication in RFC 3261 that 
Priority is supposed to be a strictly ordered set. If we want to go down 
the path of redefining semantics for parts of RFC 3261, then we're 
looking at a much, much larger effort than I envisioned for this document.

All I'm intending to do here is set up an IANA registry.
