Hi Colin,
After a careful reread of dccp-rtp, here are my comments. Modulo these
pretty nitty comments, I support the draft.
There are a couple of places where you use lower-case "should" where
maybe you mean "SHOULD", or some other word would be clearer:

I agree with all your suggestions. I'll submit an update
incorporating them, and any other comments, when the working group
last call ends.

Hi,
Some WG last call comments:
A. Section 4.4:
In the case an RTP session bridges multiple DCCP connections it might be
worth noting that support of TMMBR from draft-ietf-avt-ccm could help. I
would suggest including an informative reference to it.
B. Section 5.2:
There need to be a stateme

Great, that addresses my comment then.

I am happy with the changes made and I have no other issues pertaining to

You mean a normative statement that the grammar in section 5.2 is
specified using ABNF as defined in RFC 4234?
Yes.

Linux has translated DCCP for
more like TCP in this regard than UDP, I'd
expect.
