This is interesting.  I have always thought of AT as being 3rd party -- or else all closed functionality will become open when you add the alternate access that the closed functionality requires -- which then triggers the need to expose information to AT but you can't - because it is closed to outside AT.  

OR you have closed functionality (to third party AT) but it is labelled as not closed because you have some (but not all ) built in AT.  

So I think it is best to either not define built in accessibility as AT.   OR define closed functionality as lack of access by 3rd party AT.
