Sorry for being late in this thread, but here are my "two cents".

I agree with Gregg and Peter. The non-web non-embedded content can be
closed (by DRM) to accessibility features such as speech output. Of course
it is the user agent who will make this "closure" happen. But if the
content has the "voice output disabled" bit, then the user agent will be
unable to provide non-visual access (of course, if the user agent behaves
properly according to DRM). And, as Peter says, this is a "classical"
example of "closed by policy".

To me this is not different to interactivity. Non-web non-embedded content,
according to our definition, can be interactive, but the interactivity will
only happen when the user agent is presenting the content.

Best regards,
