No, I understand.

Yes.

Yes, but I think we only need the simplest possible approach. For anything  
more powerful, people should use a "proper vocabulary" that covers more  
than our simplifying assumptions.

I don't mean this to be disparaging. But I think all relationships beyond  
"this is a version of that" are a field where others do good work, and we  
should defer to them as needed.

Agreed.

I believe it aint necessarily so. A person looking for content to use  
themselves is likely to be interested in whether it works with the  
assistive technology they require, but fairly uninterested in all the work  
that has been done for all other kinds of assistive technology.

A teacher, employer, or similar person selecting content on behalf of a  
large group is likely to want some general assurance that a work has been  
thoughtfully developed.

True, but if we enable people to get discovered for all the work they have  
done, it is pretty clearly in their interest to identify who can benefit  
 from their work.

In this case, I think we're in the latter situation. But as noted earlier,  
I don't think this is the first priority...
