One could imagine the lock applying to the resource and to all its 
bindings, considering  the bindings to be part of the state of the 
resource.  If I recall, I think this is the model I'd always assumed 
until GULP.  With this model, if A and B are bindings to a resource, 
and a LOCK token to A is successful, then for the duration of the lock 
the token is required to change either A or B.

In today's server implementations, does a LOCK of depth 0 on a 
collection prevent MOVE from being used to change resource names inside 
the collection?  This is another possible case that might be different 
depending on whether bindings were considered part of the collection, 
part of the resource state, or both.
