Wait for Event with Correlation

[Mike Pokraka]

Hi Mark,
Apparently the main reason correlation came to be was for XI. The idea 
is kindof a wait for event with non-key data; where the waiter is the 
key rather than the waitee (yes I'm making these terms up). The waitee 
contains the waiter's key as an attribute.

One real-world situ where I would have liked to have used it in a non-XI 
environment is a "wait for credit" function for an invoice. I have no 
idea what the credit's key is, but when it gets posted, IT will have the 
key to the invoice object which is waiting for an event. Correlation 
will relate it back and trip the wait step.

Something like that anyway...

Cheers
Mike
