9.10.3 says:

   If the prefix is not
   present, the namespace of the identityref is the default namespace
   in effect on the element that contains the identityref value.


so the interpretation of a missing prefix in "fooref" is that the
identity is defined in module B.

(a missing prefix in "foo" means that the identity is defined in
module A)
