I had completely forgotten about this one, thanks for the pointer! Indeed this could be used to map receipts for SIP MESSAGE. Now, this is in a different spec to that which defines SIP MESSAGE, whereas MSRP reporting is baked into the protocol itself. Personally, I would define th empaling for MSRP, because REPORT is part of the protocol, and leave it out from IM, at least for the moment.

Peter added this to his slides, so I guess we'll discuss it in today's meeting.
