Makes sense to me in case of open captions burned onto the video track.
and (b) styling of elements at the HTML level ('this video can be
asked to display captions').
I don't quite understand how this would work. Closed captioning
availability seems more like an intrinsic feature of the video file
and the preference to have captions rendered seems like a boolean
pref--not style.
Actually, I over-spoke when I said the formal word "style"; we just
mean that the user preference for assistive material should be
conveyed to the multimedia player and resource, after the HTML-level
selection has happened: "Once a candidate source has been selected,
the UA must attempt to apply the user's accessibility preferences to
its presentation, so that adaptable content is presented
appropriately."
