Asaf,

Basically we receive an epr in the subscribe request which
points us at 
the resource to send notifications to....

This is as per spec...

If you want to look at code, then take a look at
SubscriptionHome in the 
.../v2004_06 package  (too long to write 
)....There you will see us 
extract the EPR from the request.....
