Having mixed language cues is actually also something I'd like to see
solved, in particular for selecting the right font. If e.g. a Chinese
word was displayed right in the middle of some English captions, it
should be marked up properly. Maybe we can use <c> for this with a
@lang attribute e.g. <c lang="zh">? I think I would prefer that over
introducing another span-like element.
