ISTM the real problem is with language tags in video media. These could 
indicate that the lip motions of people in the video reflect speakers of 
the tagged language. Or they could indicate written text in the 
specified language is embedded in the video. (Could be closed caption 
text or just signage.) Or (in the case of signed language tags) it could 
indicate use of sign language in the video.

But in the end, if this is declarative about what is being sent then it 
isn't clear whether it is important. If it is an indication of what is 
being requested, then it is more important.
