Re: [Bug 13357] <video>: Additional AudioTrack.kind categories are needed to identify tracks where audio descriptions are premixed with main dialogue.

I guess I would still like to look at the possibility that we can define a set of keywords, and that 'kind' can be a number of those concatenated with "+", such as

main+description (as here)
video: main+sign (when sign-language 'audio' is overlayed into the main video)
video: main+captions (captions 'burned in')

and so on…
