>To my knowledge the necessary signalling is in place for all other types of
RTCP reporting. The AVPF defines SDP attribute that allows control of the
usage of the formats within that proposal. So I donīt think arguing that it
is a general problem would lessen the need for SDP attributes in regards to
XR formats.

[Alan] I don't recall seeing any explicit means of turning RTCP reports on
and off and was only able to locate an expired draft on using SDP to
negotiate RTCP bandwidth.  It would be helpful if you could provide some
references to existing signalling protocols.

>By supporting SDP you support the basic signalling that are currenlty in
use by the most common real-time media applications using RTP/RTCP. SIP uses
SDP, RTSP uses SDP.

[Alan] How about H.323?
