In general, you can't display *all* bindings to a resource. There may be 
an infinite number (if a parent collection has a bind loop).

It returns all bindings (each with a URI to the collection it's in). If 
you need to compute all *paths*, you'll need to redo that step 
recursively for these collections.

Yes, if it needs to. It just has to keep in mind that doing it without 
special loop checks may result in an infinite loop.
