Then let's try and tackle it.

The spec already has to deal with lifetime semantics of locally scoped 
variables and correlation sets. Let's assume that partner links are 
another type of scoped variable accessed (read/write) like any other 
locally or globally declared variable. That would cover the lifetime and 
access semantics. The spec also handles the case where multiple partner 
links are based on the same partner link type. We can extend that to the 
myRole EPR of a locally declared partner link (i.e. unique EPR in each 

What other problems are we going to run into?
