Re: aside and figure elements

Also note that if we do

	<figure role="img">
		<img src="image" role="presentation" >
    	<summary>Description</summary>
	</figure>

then <figure>, just like the WAI-ARIA example, groups *two* elements  - 
<summary> and <img>.

PS: We really *must* define <figure> so that it - in general - is 
unnecessary to use aria-labelledby for designating the caption. Just as 
for the <caption> of <table>, it should be self evident what <figure>'s 
caption element is captioning.

And this begs the question: What role does <table>'s <caption> element 
have? The best match I could find was the abstract role "sectionhead":

A structure that labels or summarizes the topic of its related section.
