Do you have a preference on the character used? I think the following 
are on the table:

   context/##dc/title

   context/**dc/title

   context/::dc/title

Could be another as well.

What was the reasoning behind selecting @@ for the view namespace 
shortcut? (IIRC, the motivation was to use characters that could be used 
in URLs, but I'm not sure that's an issue for adapters...or is it?)
