[AVTCORE] AD Evaluation of draft-ietf-avtcore-multi-media-rtp-session-10

["Ben Campbell" <[e-mail]>]

(resent with the working group address unborked. Apologies for the 
repeat.)

Hi,

Here is my AD evaluation of 
draft-ietf-avtcore-multi-media-rtp-session-10. The first substantive 
comment has consequences on how we do the IETF last call, so we need to 
resolve it prior to the last call.

Thanks!

Ben.

Substantive Comments:
=====================

- Section 4, "Equal treatment of media."

This section is made effectively normative by the "MUST" in the 
preamble. But the guidance under "Equal treatment" is a bit on the fuzzy 
side for normative requirements. And since the detailed guidance is 
delegated to the two references at the end of this section, they should 
be normative references. This is a bit problematic since they are 
informational drafts. Now, that's not a show stopper; if the references 
should be normative we can make them so--it just requires a bit more 
process.

So, please consider whether the section should be tightened up and the 
references made normative, or if it can be restated as non-normative 
guidance. This impacts how we do the IETF last call announcement, so I 
will hold the last call until we resolve it.

- 6.2, third paragraph:

5956 obsoletes 4756. Is there a need to keep the reference to 4656? 
(e.g. backwards compatibility?)

Editorial and Nits:
===================

- section 2: IDNits points out that the draft uses “NOT 
RECOMMENDED”, but does not mention it here.

- 5.3, 2nd paragraph:

s/"stream on the same SSRC"/"stream with the same SSRC"
