I am not sure if this means you want to change this somehow or that you are
going to update the draft with TCP/DTLS/BFCP. I agree that the syntax is
not ideal but it is in line with other documents such as dtls-sdp or
sctp-sdp.

The id-nits checker made me aware of RFC 8122 obsoleting RFC 4572, I reckon

draft-ietf-mmusic-4572-update is now published as RFC 8122, so references
to RFC 4572 should be updated to RFC 8122

The rest sounds good.

When you publish the updated version I will review and provide comments. I
will also sync comments which were made against the ICE Considerations
section of sctp-sdp with your draft.
