The only implementation (i know of ) for figure/figcaption is in firefox
which is implemented like this: (using aria notation for demonstration
purposes actually uses IA2 caption role)

<figure aria-labelledby="caption" role="group">

 some content

<figcaption id="caption" role="caption">caption text</figcaption>

<figure>

Only IA2 has a caption role (AFAIK), and think it would be useful to be
able to provide the role via ARIA.

anwyay am raising this again for consideration in ARIA 1.1
