I'm not sure why an EPR would have to be limited to being used only in
transitory cases. If it's limited in that way, IMO it just means that something
else quite like an EPR will need to be devised for the non-transitory cases.
That seems like a mistake.

There isn't currently a mapping from WSA to UDDI, although I am not sure
that one will be needed.  A lot of times an EPR will be part of an
interaction.  Node A sends B a message and includes a ReplyTo EPR specifying
where a response should be sent.

I am still not convinced that EPR are intended to be "stored" in the same
way that services are saved to a UDDI Registry.  EPRs seem to be more
transitory in nature.

The discussion on physical vs. logical addresses is interesting in this
context.  From my perspective the physical address (transport specific
location) should be stored, but the logical address (the ERP) likely will
not need to be.

It will be interesting to see what happens in practice in this area.  As a
working group we will have a lot of educating to do to ensure the
specification is used as designed.

Is their a specification that show how a service can discover an existing
EPR? Is their a UDDI binding defined for WSA-Core? 

In general, how can one discover/search for an EPR without an hallway
conversation? 

Thanks
