Randall,

1. You dropped one sentence from the first paragraph in my latest proposal:

"A non-sign language tag with video media is interpreted as a view of a
  speaking person."

It was a result of the previous discussion and reasoning, and I think it 
should be reinserted.

2. You also changed the title proposal from " 5.4 Media, Language and 
Modality indications" to "5.4 Usage Notes"

I think it is better to have a title that tells about the topic of the 
paragraph. I suggest to use the title I proposed, but I can accept yours 
if you have a good reason for the change.

Thanks,

Gunnar
