Are EPRs identifiers?

End of call today I raised this and someone said, oh we are not
discussing MetadataExchange....

I asked this question since we used WSRF's use of WS-Addressing as a
reference data point, let's use WS-MetadataExchange for another data
point....

Question:  I have 2 EPR's, both differ only by a RefProperty, If i use
say MetadataExchange, will i get the same WSDL?

If the answer was "yes, it might be different.  E.G. different
policies." it then implies that EPR is an identifier!!!

Thanks,
