As Jim Jewett said [1] , something to keep in mind is that

John Foliot has talked of a clean, semantic, explicit association to
transcripts, text descriptions, captions, audio descriptions and/or
streams that could be toggled on or off by the end user. I have tried
to capture some of that in the Wiki. [2] He has also provided examples
that hint on some best practices that not only native players and but
HTML 5 as a whole could approach multi-media content.[3]
