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!

GF:  Just by way of information, there's a list of roles defined in DFXP/TTM at http://www.w3.org/TR/ttaf1-dfxp/#metadata-attribute-role .  I'm not sure about "textaudesc" as a role because it isn't very clear.  Despite its length, how about using textaudiodesc instead?  This is more descriptive and also brings it into line with existing nomenclature, such as SMIL's systemAudioDesc.
