Yes. And they could be in parallel to either japanese or italian.

I used to have a scheme that included only three-character words and
capitalised, but you will see in the wiki
(http://www.w3.org/WAI/PF/HTML/wiki/Media_TextAssociations) that the
current proposal stands at: "caption", "subtitle", "textaudesc",
"karaoke", "chapters", "tickertext", "lyrics" as values for role.
Feedback encouraged!
