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.] >-Madeleine > >On Tuesday, March 28, 2000, David Poehlman <poehlman@clark.net> wrote: >this new edition has the capability to play audio description on demand if >it is present. >-- >Hands-On Technolog(eye)s >ftp://ftp.clark.net/pub/poehlman >http://poehlman.clark.net >mailto:poehlman@clark.net >voice 301-949-7599 >end sig. >
