I suppose they would just read them, but of course they would be unable to read anything that is @hidden because, well, it is hidden.

Complex or less complex, the current CP is suggesting that the "longer descriptions" be place inside of a construct that would be @hidden, yet still accessible to aria-describedby. With no visual indicator or switch for the sighted user to know that there is a longer textual description (complex or simple), they would probably never even have the opportunity to read it. The only reason why I mention deafness is that at least one implementer is suggesting that the rich or simple longer description would be read aloud using VoiceOver - which is of no use to the user who is deaf. 

There are 2 possible patterns that might emerge here. The first is "inline" like this:

<img src="" aria-describedby="foo1" alt="alt text">

<div id="foo1" hidden>
 <p>Plenty of content here, which may or may not include richer content such as:</p>
 <ul>
   <li><a href="baz.html">Links</a></li>
   <li>Lists
     <ol>
      <li>Unordered</li>
      <li>Ordered</li>
      <li>Definition</li>
     </ol></li>
   <li>Tables</li>
 </ul>
</div>


The other being:

<img src="" aria-describedby="foo2" alt="alt text">

  <a href="longer_description.html" hidden>Longer textual description</a>


I'll pose the question back to you (and the larger list as well) - How do *you* think a Deaf person might access such descriptions that are @hidden but "conforming"?
