Where is the information that the UA needs to make the media objects selectable? Is that defined by RDF or some other language and is there some standard for it that the UA can use to define what object is caption and what is overdubbing or description and what language is used? When there is such a standard, is it then that when the user at UA selects to turn captions off or turn on overdubbings in one language (not original) and captions in another language (not original either) we just totally ignore the SMIL flag settings and use the original info directly? (The second case is actually impossible to state with SMIL.) If we take this approach, is there any case where the UA interface actually uses the SMIL flags? Or is that then a special lower level interface where the SMIL flags can be directly controlled and what you can do is limited and dependent of how the SMIL author decided to use the flags?
