"Round2/ExternalPolicy.xml <- externally provided test case" is 
confusing. What about:

"Round2/ExternalPolicy.xml <- externally provided policy expression"

The value of the Name attribute is an absolute IRI and is independent of the location of the XML document where the identified policy expression resides in. As such, referencing a policy expression using the Name attribute relies on additional out of band information [1].

OK, I had thought so. Of course we don't prescribe any mechanisms to 
retrieve policy expressions from non-resolvable IRIs. I have two issues 
with using this external policy in round 2:

1. Round 2 is supposed to test effective policy computation for WSDL. 
External policies don't seem to be relevant for that.

2. Some implementations may need to modify the test input files to fit 
this external policy into their processing model. There may e.g. be 
constraints that forbid an implementation to retrieve policies from an 
external file or URI. I would rather design the test cases such that 
they can always work without having to modify input documents.
