Having just re-read draft-ietf-mmusic-rid-02 from to top to bottom, I think
it's in a very good state.  I only have minor readability and editorial
comments where I think it could be improvements.


On small matters of readability:

- We use the term "RID RTP streams", which is then defined in another spec
as "source RTP Streams".  Can we just call them "source RTP streams" here
too and save the reader some indirection?

- We use the terms "constraints", "parameters" and even "constraining
parameters", which I believe all mean the same thing.  Can we just pick one
and save the reader some disambiguation?

On the open issues:

11.1 (declarative SDP): I agree with keeping the current text.

11.2 (bitrate definition): I agree with keeping the current text.

11.3 (escaping values): I agree with option #3 (let a future extension
define it, if needed).

11.4 (max-width and max-height): Either way is fine to me (included or not).

11.5 (max-fps definition): I agree with keeping the current text.


And finally, some very minor editoral things:

- The sentence "All "rid" parameters MUST be registered ... Section 12"
doesn't have a period at the end.

- The sentence "The SDP given below skips few lines" should be "The SDP
given below skips a few lines".
