Re: [w3c/wcag] Revisiting imbalance between 1.2.4 Captions (Live) (AA) and 1.2.9 Audio-only (Live) (AAA) (#795)

+1 to Patrick's thinking that this should all be addressed in Silver.

While we are at that, I'd also like to ensure that "video" actually be
re-named "multi-media" (or expanded to video and other multi-media
sources"), which would also include other forms of animation... as Patrick
described it "moving pictures with (or without) audio". For while I note
the definition of video states:

video

the technology of moving or sequenced pictures or images
NOTE
Video can be made up of animated or photographic images, or both.

...it has been my observation that many evaluators take "video" to also be
synonymous with "mp4" (which is a false assertion). I could argue that
animated gifs *might* be in scope, as well as animated SVG
<https://en.wikipedia.org/wiki/SVG_animation> content.

Additionally, I was in conversation with a developer earlier this week who
is working on a standardized 'bot' language
<https://www.w3.org/community/conv/>, and his PoC can be scripted such that
the bot can provide 'animated' responses to input ("Avatar asks 'which
door', and when you say left it goes to the left door..."). Is that a
video? Does it need audio description?
