Do we need to make any further clarifications for the references to CEMA?
Section 5.1.1.2 has a sentence that is a little awkward, but seems to be saying the CEMA is out of scope.
But in section 6 for gateway function it mentions CEMA can be used.

My understanding is I think section 6 suggests to use CEMA equivalent procedures without CEMA attributes!

Also, in section 6 should we add a further statement that the gateway assumes one MSRP data channel instance and one sub-protocol per SIP dialog as RCS mandates that a single SIP session/dialog has only one MSRP m= line?


Thanks
Raju

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Multiparty Multimedia Session Control WG of the IETF.

Abstract:
   This document specifies how the Message Session Relay Protocol (MSRP)
   can be instantiated as a data channel sub-protocol, using the SDP
   offer/answer exchange-based generic data channel negotiation
   framework.  Two network configurations are documented: a WebRTC end-
   to-end configuration (connecting two MSRP over data channel
   endpoints), and a gateway configuration (connecting an MSRP over data
   channel endpoint with an MSRP over TCP or TLS endpoint).
