Again, I don't want to talk on behalf of the authors but my
understanding is that although you are not allowed to reason about the
semantics of their contents, you are allowed to reason about their
values for comparison reasons.

So, EPR1 and EPR2 point to the same service (hence, they have the same
policies, wsdl description, etc.) if their Address and
ReferenceProperties are the same (the Parameters can be different).

You can have EPR3 and EPR4 with the same Address and ReferenceParameters
but the reference services may have different policies, wsdl, other
metadata because their ReferenceProperties are different.

However, the difference is that although you are allowed to check the
contents of the EPRs for comparison purposes, you shouldn't interpret
the values to mean anything (since they are service-specific).

At least that's my understanding.

.savas.
