It's highlighted elsewhere but it's worth a reminder that this terminology
is not consistently used globally.

In the UK and much of Europe "subtitles" are used both for text intended
for hard of hearing and for translation purposes and "captions" are labels
that appear burned into video, for example the name of a contributor on a
news programme on a banner at the bottom of the screen.

For clarity I have come to use the words "caption" and "subtitle"
interchangeably in the context of accessibility and to qualify this with
the intended purpose e.g. "hard of hearing subtitles", "translation
subtitles" etc.

It's okay for a W3C document like MAUR or HTML to define its own usage
internally and reference its own terms; attempting to force these on the
world at large is unlikely to succeed when there is so much prior usage of
the same terms.

"Subtitles" are also mini titles that appear underneath main headings!

Kind regards,
