Hi Tom,

Thanks for incorporating the changes. The dtls-id change looks good. Unfortunately, the MUX category change suffers from the fact we are chasing a moving target. draft-ietf-mmusic-sdp-mux-attributes was updated recently and the NOT RECOMMENDED category was replaced with the CAUTION category.

Upon taking another look at draft-ietf-mmusic-sdp-mux-attributes, my previous suggestion was not good. draft-ietf-mmusic-sdp-mux-attributes already defines the Mux category for all SDP attribute defined in rfc4583bis except the newly added bfcpver SDP attribute. For this, I think the Mux category should be IDENTICAL. However, I’m not sure if it should be added to rfc4583bis or to draft-ietf-mmusic-sdp-mux-attributes directly. I have cc’d Suhas to Christer to get their input, both on the mux category selected and where it should be specified.

As for multiplexing of BFCP lines, perhaps rfc4583bis should simply say, "Multiplexing of BFCP ‘m' lines, as defined in BUNDLE [16], is not defined by this specification.”
If we agree to this, the reference to BUNDLE should be Informational instead of Normative.

Cheers,
Charles

Incorporates the two issues spotted by Charles in the -14 version. The draft should most likely and hopefully be ready to proceed through the next stages now.
