Bernard,

We had a reasoning yesterday that it is so unusual to provide text in a 
conversational video call in the video media stream that we could leave 
that usage undefined (it was used as mixed into the video image from the 
sending side in the early 2000s, and it is also possible to send text 
coded text elements in RFC 3640 MPEG4 video coding for presentation in 
the receiving end, but the impression is that these methods are not used 
nowadays in conversational calls) That leaves the only practically used 
case for non-sign language in video media in conversational calls be for 
a view of spoken language.
Randall introduced that view (about captions in video not being used in 
conversational calls) and I agreed. I know that is not total consensus, 
but there were at least not any declared conflicting views.

There are use cases for the use of a view of a speaking person in video.

It would be good if this reasoning makes you change your mind and check 
if we can have consensus for inserting the dropped sentence.

If not, I will stop arguing for that and accept that we need to take the 
effort to define how to indicate this use case at a later stage. The 
rest of section 5.4 is good now and explicitly allows further work and 
application agreements.
