aria-hidden for content outside modal dialog?

Hi, all.

I just wanted to make sure I was conceptualizing something properly. In a
modal dialog, one should apply aria-hidden to all content not in the dialog
itself, right? Applying aria-hidden only to focusable elements outside the
dialog would not be sufficient, since one could still read the full
contents of the page using the Virtual PC Cursor in JAWS or Browse mode in
NVDA, etc. Or is that not a big deal, or expected behavior? Any sense of
things here?

On a side note, if this is the case, then that means that usually dialogs
will not be able to be inserted in situ on the page at a point right after
their triggering control, since, I think, you cannot have an element with
aria-hidden="false" within an element with aria-hidden="true".

Thanks,
Rob
