In a multitrack API, since caption tracks are essentially the audio for Deaf and HoH use, we will need some way for these to follow the selected audio asset. If I have a presentation, with the option of switching to different a different audio resource (e.g director commentary which is longer, starts before and ends after the main movie). The captions for it need to be timed to the commentary audio, and so if it's in a markup element, live in that element. If the user has captions turned on and wants the commentary audio, then the captions for the commentary soundtrack will need to replace the captions for the original audio track, and render into the rectangle allotted for the main video. I'm not seeing how I would create this.
