Ordering Question

[Jan Algermissen <algermissen1971@mac.com>]

Hi,

I have a question rearding the ordering process described by UBL 2.0:

If the seller party modifies an order and thus replies to an Order  
with an OrderResponse and if the buyer chooses to accept the modified  
order (thereby reaching one of the two end states of the ordering  
process) how does the seller know that the buyer accepted the  
modified offer?

Generaly speaking:

IIUC, the only way for the seller to know the end state of the buyer  
is via the OrderResponseSimple, where the seller kows the buyers  
state because it is simply represented by the previous Order message.

Thanks for any help.

Jan
