Though I am not yet in agreement with Steve, I think, Shelley, that you 
are wrong here. See below.

I think we need to work out in much more detail how we envision 
<figure> to be used. It is clear that we all have quite different ideas.

You yourself have quoted the example from WAI-ARIA (because you 
recommend using @role and aria-* rather than <figure>), where there is 
a caption *and* the image has role="presentation". Sorry, but I quote 
it again:

<div role="img" aria-labelledby="caption">
  <img src="example.png" role="presentation" alt="">
  <p id="caption">A visible text caption labeling the image.</p>

So even if the one - or all - <img> elements of a <figure> are defined 
to have role="presentation", that doesn't mean that the image as such 
is presentational.
