The SIP, SIPPING and MEDIACTRL chairs (or at least a representative collection 
of them) did get together to consider this issue, and decided that as the work 
(as currently proposed) did not in fact extend SIP, that MEDIACTRL should 
retain the work. 

SDP extensions are proposed to MMUSIC, and that would appear to be appropriate.

At some point when the work is complete enough for review, it was agreed that 
RAI wide review of this document should occur, and one of the review experts in 
the SIP WG will be jumped on at that point to review the solution.

We did not discuss whether the solution adopted by the draft was the correct 
solution - if people in the SIP WG have concerns, then please address them to 
the MEDIACTRL WG. If you are not participants in that WG then we (the SIP 
chairs) will be pleased to forward on comments.

Regards

Keith

PS: My understanding of the various charters is that SIP does not generate 
requirements for development of SIP, except in the security area. However it 
can charter work based on requirements from any appropriate working group, 
which includes among others, both SIPPING and MEDIACTRL. I suspect the ADs 
would want to be confident that the appropriate experts had contributed to the 
appropriate requirements.

        My opinion is that those requirements need to go to sipping first for 
discussion as sipping is, as I understand it, chartered to agree on 
requirements before any extension work is taken up by the sip wg.

                group to take on the work of meeting those requirements.
                
                Here's a link to the draft:

                Do you folks think these requirements are sufficiently cooked 
to work
                with, or do we need to punt this football back to the senders or
                perhaps lateral it to SIPPING for a little more thought?
