Actually this use case is for what's called "subtitles," which differ
from captions by not including information about key, nonverbal sonic
events.

We spent some time during the MAUR 1.0 process exploring whether we
could somehow combine subtitle and caption, but that effort was
categorically rejected. It seems the subtitle using public would not
accept textual information about key sonic events, which they're assumed
to be able to hear perfectly well.

Best,

This use case came up during our discussions in the HTML Working Group prior to the release of HTML 5.0. Let me know if you need a reference to those minutes, and I'll dig them up for you. This use case isn't noted in the Media Accessibility User Requirements (MAUR) note simply because it's not an accessibility use case in the traditional sense.
