Thanks for the review Mark.

Yes, there isn't much to discuss in this regards as this is a media type
for a RTP payload format. You need some external signalling mechanism
that either declare or negotiate the features to use. The only
interoperability issue here is the support and usage of interleaving.
Which is covered in the draft. So what could be done is to add a
reference to the relative sections in the RTP payload format.

No, there are ongoing work to define file storage of the G.719 codec.
However, that is as part of the ISO based media file format. Thus this
media type is not going to be used as a file type at all. And if it is
this media type will need an update.
