Ordering Process - help request

["Stephen Green" <stephen_green@bristol-city.gov.uk>]

If anyone could help a little with my attempt
to get to grips with the example and how it's
conditions might work for UBL; 
I've got a little way with how to represent 
ordering (just the sales order so far). I'm just
not sure of how best to handle the fact that
a sales order could be rejected, accepted or
partly accepted. I've attached what I've done
- could someone help me with how best to
handle, whether by 'decision', 'fork' or whatever,
the option of these two possible successful order
responses. 
(Please see attached with "<!-- ... -->" in the
BusinessCollaboration where I got stuck.)
(Note: This could be the beginning of a SBS
definition for ordering perhaps too)

Many thanks

Steve
