Hmm. Me too. (I realise that is not usually very helpful, but I basically agree with Al entirely. Note that there are plenty of other posssible scenarios, not least of which are poeple trying to work together...)

We need your consensus to prod PF into taking the position that _all_ of these things belong as 'bag' semantics where a multiple selection is possible in the base-level definition, and the "pick only one" behavior is not the base definition but an overlaid default, which can be rolled back by the right kind of user intervention. For a concrete scenario (just one stab): The person wishing both captions and audio descriptions has some hearing loss but not total; and also enough vision impairment to use a screen magnifier. The captions are necessary because in this cinema_verite the dialog is in barely decipherable grunts, while the audio descriptions are articulated with a bell-like tone that needs no text alternative. So the user processes the dialog in audio+caption+magnifier and catches up with what the magnifier leaves out by the audio descriptions in audio. [The generic answer is that "both" ususally involves a scenario with a user with functional impairment, but not total functional loss, in two modes.]
