I prefer this notation, even though it's more verbose. I think it should 
be supported along with a short cut syntax.

This problem seems analogous to view lookup -- 
"content/++view++index.html" and "content/@@index.html" are equivalent.

So, applied to adapters, we could use:

   content/++adapter++dc/title (or '++adapt++')

one could use:

   content/##dc/title

or perhaps (yuckier):

   content/**dc/title

I'd hate to see Yet Another Traversal Syntax introduced when we already 
have a decent pattern established.
