The WGLC and adoption deadline has now passed for 
draft-roach-sipcore-priority-00. Nine people (other than chairs and 
authors) made meaningful comments.

I conclude there is consensus to adopt this draft as a wg document.

Regarding WGLC, two notable issues were raised, and I don't yet see a 
clear consensus on those issues:

- should there be a registration template?
   Christer advocates this, Keith opposes, Adam finds it unnecessary.

- should this document also spell out the semantics of all the priority
   values defined in 3261? (Currently it only defines "emergency".)
   Dan, James, and Roy in favor, Adam and I prefer not to do it *in this
   document*.

So, I will ask Adam to submit a wg draft version of this document, 
otherwise unchanged.

While he is doing that, I would like to get a broader consensus on the 
issues above. I'll post a separate question on each of those, to keep 
the discussions separate.

	Thanks,
	Paul
