I am "on leave" from the HTMLwg for a month, but I have just 
proposed (on Twitter) using <caption role="summary"> to 
disambiguate captions from "summary captions". (I hope this 
message still reaches the mailinglist ...)

OK, I don't know what role="" value to use - may be 
role="contentinfo" or may be something new? (The good thing about 
suggesting to use role="" is that WAI-ARIA, which currently has 
much of the accessibility attention, can then think about the 
issue and specify it better than in HTML 4!)

Test case with discussion: http://malform.no/html5/caption+role

Some advantages I would mention: Extremely compatible with legacy 
_visual_ user agents (don't know about screen readers - but one 
should think that, with attention ARIA has, that it would be 
rather compatible). Plus that authors easily can change to 
hide/show such summaries to all users.
