Re: [g-a-devel] HTML 5 figure and figcaption elements.

[Alexander Surkov <surkov alexander gmail com>]

Hi. Figure element is supposed to contain or group illustrations,
diagrams and etc so role_image is inside a figure accessible.
Originally I tempted to say we don't need an accessible for a figure
and we should expose the underlying image labelled by figcaption
element but that seems doesn't work well when figure is used to group
a set of images or diagrams.

I think when AT sees a figure accessible then it should announce this
is a figure and the figure name obtained from figcaption accessible
and then allow user to go into the figure to pick up underlying
elements. It's used to introduce a sort of new level of abstraction so
that the user goes into it when he's interested in details. For
example:

<figure>
  <figcaption>Alhambra</figcaption>
  <img src="alhambra.jpg" alt="A room of the palace and a view of the
Court of the Lions.">
</figure>

Thanks.
Alex.
