Err, I don't believe that this is the case.

Specifically, it is possible (and in fact an example is given in the 
WSDL 1.1 specification) to "partition" a WSDL into pieces, all of which 
have the same namespace.  In other words, a WSDL 1.1 document can import 
another WSDL 1.1 document that has the same namespace as the importing 
document, and the practice is more or less recommended in the WSDL 1.1 
specification as a means of modularizing definitions.

WSDL 1.1 does not, as I understand it, specify behavior in cases in 
which an import redefines an existing definition, if those definitions 
differ.

Consequently, while it may be possible to create ambiguous pointers due 
to the multi-purpose import/include/dessert-wax nature of WSDL 1.1 
import, that ambiguity is going to reflect ambiguity within the set of 
documents.  Arguably, broken pointers are better suited for broken 
documents than working ones.  Right?  :-)

Amy!
