Re: [html-techs-tf] caption vs alt

As I see it, the figure element is a tool for supporting SC 1.3.1 and
the figcaption's  primary purpose is to label the figure;  that it can
be used to label an image within is secondary if not incidental.
The text identifier for the group might be an adequate label for the
image but as others have pointed out it is important for the imgg to
be exposed as an image or graphic.
If there were a batch of pictures uploaded with no ability to add alt,
I suppose they should all be in a single figure element (as a group)
or they should be marked up with li in a single ul/ol.
I refer to the figure/figcaption example with "clara.jpg, taken on
12/11/2010" and such on 4.7 Embedded content — HTML 5.1 Nightly page
referred to in an earlier email by Steve.
It would be poor experience if every image were in a separate figure element.

I do not see why it is critical to:
- group an image with a grouping element when the figure has no other
content than an img and a figcaption. What is being grouped together?
- and to grant an exception for not using alt only in this situation.
It simply complicates matters for developers and testers.

I modified Ramón's example as under:
 <div role="group" aria-labelledby="fig">
   <img src="einstein.jpg" alt="Albert Einstein" />
   <span id="fig">Albert Einstein</span>
 </div>
AT behavior is no different.

Ramón: In my experience JAWS14/15 (with FF) announces both figure and
the div with role=group  as a group and not as a frame.
Thanks and regards,
Sailesh
