I have read rid-07, and the technical contents look good.

One philosophical question: is there any expectation that anyone will actually use rid without simulcast? Is it useful at all, if you can’t rely on the peer supporting rid?  (SDP’s lack of comprehension-mandatory strikes again.)

On the IANA registration, I think there are enough constraints on what the specification requires that the registration policy for the RID-level parameters needs to be “Expert Review”, rather than “Specification Required.”  Some of the requirements this puts on the required specification — particularly, on parameter ABNF compatibility — aren’t something that we can reasonably require IANA itself to verify.
