Summary: Ready (with nits) for publication as Experimental.

David's shepherd writeup points out that implementation and usage 
experience is desired before producing a proposed standard. Are there 
any points of concern about how this might behave (or misbehave) in a 
deployed network that such experience would inform? If so, it would be 
useful to call them out in the document.

It would be nicer if the document argued why there are no new security 
considerations introduced by the new behavior defined in this draft, 
rather than tacitly asserting that there aren't any.

The terminology section has lots of 2119 words in it. It's hard to tell 
when these have been copied from some other draft (and this is just 
restating them) vs when this draft is introducing a new requirement. 
Since a new requirement would likely be missed if it appeared only in a 
terminology section, would it be feasible to make sure anything new is 
well covered in section 3 or 4 and remove 2119 from these definitions 
altogether?

The rest of these comments are minor editorial nits:

Section 1.2, paragraph 3: "Intserv over Diffserv can operate over a 
statically provisioned Diffserv region or RSVP aware." is missing a a 
word somewhere.

Section 1.2 paragraph 4: "By using multiple aggregate reservations for 
the same PHB allows enforcement of the different preemption priorities 
within the aggregation region." doesn't parse. Should the initial "By" 
be deleted?

The definition for PCN-domain is very close to circular. Perhaps some 
words can be removed?
