You say that a @longdesc can serve as discrete link, right? And, yes it 

I don't support <desc>. And never loved that idea. And after this 
debate, I think I am ready to limit the fallback of <picture> to 
alternative text, by what I mean to limit it to "short description". 
Because, like Peter said: by offering alternative text in the form of 
fallback content/elements, one could e.g. declare the language for 
different words in the fallback. This is not possible if we limit the 
fallback to <img> alone. 

It would also be possible to include an anchor element to a longer 

I would suggest that the spec should allow authors a choice: Either to 
use <img> (that is: @longdesc and @alt) for the alternative text and 
longdesc link. But that they also should be permitted to place the 
same, short text in mark-up in the fallback. What do you think about 
such an idea?
