The difference is that <caption> will never work, because of things like 
this:

   <table>
     <caption>
        <figure>
           <img ...>
           <caption> ...A... </caption>
        </figure>
     </caption>
     ...
   </table>

...which, for legacy compatibility reasons, must result in a DOM where the 
text with "A" ends up in a second <caption> element that is a child of the 
<table> element.


The idea of having markup of this form:

   <-container->
     <-embedded-content-/>
     <-caption-> ... </-caption->
   </-container->

...is a fine idea, however, which has been proposed multiple times, and 
I'm sure we'll use some variant on that. We just can't use <caption>. Or 
<label>, because that's for form controls.

I imagine we'll use <legend>. Parsers are a bit erratic with it right now, 
but we're requiring them to shape up for the parser part of the spec 
already, and the <details> element uses it already.
