Even if it is not from our application area - conversational calls, and not initiated by SDP, and not using a video media stream, but a multiplexed RTMP TCP based message stream with interleaved video chunks and text chunks, it is an example that reminds us that something similar could be set up in a conversational call with SDP and using video media with MPEG4 according to RFC 3640, 4337 or 6381. That indicates to us that we have cases that are even less supported by our current draft. The video/mp4 media can contain video and audio and text. If that is used for a conversational call, we would need to collect 'hlang' attributes for all three modalities in the video media description, and possibly get them all agreed, and that is against one of our basic statements in section 3: (Negotiating multiple simultaneous languages within a media stream is out of scope of this document.) So, ok, let us for now assume that we limit the application to traditional conversational calls with one media and language per stream and no multiplexing.
