Document: draft-polk-local-emergency-rph-namespace-01
Reviewer: David L. Black
Review Date: July 12, 2011
IETF LC End Date: July 13, 2011

Summary:
This draft is basically ready for publication, but has nits that should be fixed before publication.

This draft defines a SIP Resource Priority header namespace, "esnet", for use in
providing preferential treatment to emergency calls (e.g., from on-scene responders).

This field is an addition to rather than a replacement for existing notions of
priority in the SIP Resource Priority header.  Section 2 explains why this was
done, but section 2 is a bit sloppy and imprecise.  Some level of imprecision is
necessary as this draft deliberately does not specify how this header namespace
is used to provide preferential treatment.  Nonetheless, the following two items
could be improved in Section 2's discussion:

1) Explain the reason for including the second paragraph, the paragraph
	that references RFC 4412's discouragement of modification of priorities
	within an administrative domain.  That paragraph's not connected to the
	rest of section 2.
2) Explicitly state that one of the anticipated uses of the priorities in the
	esnet namespace is to override the ordinary priorities found elsewhere in
	the Resource Priority header.

Small nit: There's an extraneous "to" in the first line of section 3:

   The "esnet" namespace should not to be considered generic for all
                                    ^^

idnits 2.12.12 found a few formatting problems:

  == You're using the IETF Trust Provisions' Section 6.b License Notice from
     12 Sep 2009 rather than the newer Notice from 28 Dec 2009.  (See
     http://trustee.ietf.org/license-info/)

  == It seems as if not all pages are separated by form feeds - found 0 form
     feeds but 7 pages

  == The copyright year in the IETF Trust and authors Copyright Line does not
     match the current year


Thanks,
