Re: [sipcore] Establishing a "Priority" header field registry

I have reviewed the document and saw no issues with the current contents. It performs a useful function and should be proceeded with.

As the document stands, I still see no reason why the document should update RFC 3261. It makes no normative changes within the scope of RFC 3261, which is to define the protocol between two entities.

Part of this discussion may relate to whether one sees the creation and entry of material into IANA registries as being a normative action or not. I don't. To me they are just the housekeeping that has to be done.

As regards the template (which other mails have suggested), we possibly do not need one.

Part of this down to the level of review that is required; in the document this is set as IETF review. At this level, an RFC has to exist and go through IETF community review. There will be enough people around in this process to ensure that all the information that people need to see outside the IANA table actually exists. Conversely where we are allocating values on expert review, a template could be essential if only to ensure the expert doing the review has enough information available to perform the review; that information may well exceed the information that needs to appear in the template itself.

Note that I did have a discussion with IANA on both these issues, and it would be wrong to say an opinion was expressed, Michelle seemed to be in alignment with these points.
