   I'm not aware of the problem. The worst that seems to happen when you
use a <label for=""> element with an <img> is that the <label> element
becomes just a stylable inline element. That would seem to be the best
fallback styling we can hope for in a caption/label. If you're referring
to focus passing, WF2 already places platform-specific limits on user
agents that prevent focus passing in certain situations. Because most
platforms don't give an image focus when you click on it's label (or
caption), WF2 would indirectly define <label> as not passing focus in
that situation.

   I was actually thinking of something like this:

| <figure>
|   <img id="imageid" [...]>
|   <label for="imageid">
|     Image caption text.
|   </label>
| <figure>

   ...Where fallback content is ignored by <figure>:

| <figure>
|   <table>
|     <tr><td>
|       <img id="imageid" [...]>
|     </td></tr>
|     <tr><th>
|       <label for="imageid">
|         Image caption text.
|       </label>
|     </th></tr>
|   </table>
| <figure>

   So, in the above, the UA would treat the second example as if it
where the first.
