Both of these approaches would appear to be supported by most Electronic Documents,  and browsing and searching of help functions would appear to allow locating major sections in software as well.

GV:   can't do that.  But what we CAN do is to say that for xy there is no accessibility supported way to do z or something like that.  That  would indicate (if we determine this) that there is no way to do this for some major type of content.  (Or types).     (should not be some strange fringe case) 

Then the Access Board  and m376 can do their job.

I'm not sure if that is true here though.    But if it is -- that is the way we can deal with it.
