It is subtle --but you have to lay the responsibility for access to closed functionality on the ENTITY that does the closing ---  the software author or the content author. 

If the CONTENT author chooses to use a DRM for which there are no accessible readers -- then they are closing the content - no matter what reader reads it.   They would be responsible for creating a presentation mode within the content that could meet the "closed functionality" rules or they would fail to meet the accessibility rules. 

If the CONTENT author chose a DRM for which there WERE accessible readers - then its contents would be closed but it would meet the SC through the features in the reader (the content is closed and the author met his responsibilities via having readers that provide access (presuming they meet the guidelines)     --  UNLESS the content author sets a flag that forbad the player from using those features.  Then the content would both be closed and the author would have closed out the player functionality that could have caused it to meet the 'closed functionality' features.   The author would then be responsible again for providing access in some other way. 

If the CONTENT author does not use DRM and there are accessible readers - but the software doesn’t allow AT access then it is the software's problem and the software needs to be accessible. 

'in short
if a player company wants to sell players to the gov (that meet access regs) - they need to be accessible players  (either work with AT or have built in access features).

if a content company wants to sell to the gov (and meet access regs) - they need to sell content that works with accessible players (either that work with AT or have built in)  AND they need to not set any bits that forbid the player from using its access features. 

The question is:
can players meet access regs if they honor the" do not provide access" flag
one answer - sure,  they allow access, it is the content that turns their 'do not provide access' feature
other answer - that is like putting cash on the windowsill and arresting someone for stealing it.  Why have the feature if you don't expect  it to get used and people to get shut out.    Also if the gov wants access they shouldn’t allow purchase of something that allows books to refuse to be accessed. 
THIS is a tough question
