Yes, this is another issue.  I have the same problem, somehow, with
"foo/bar->dc/title". That is "/" seems to bind more closely than "->",
probably because it's skinnier. :)  I don't have this problem with ":".


Another option is to modify the "/". For example, Evan sugested "/*", as in

   foo/bar/*dc/title

Hm

   foo/:dc/title

Sandly, nothing really jumps out as the best syntax.

So far, I like:

   foo/bar->dc/title

the best.
