Design the outlines of BPEL processes for two sites that are performing the following bidding workflow:

Site 1 decides to offer an item for sale at some offering price and sends that offer in a message to site 2. When site 2 receives that message, it decides whether it wants to accept that offer or make a new bid (at some lower price). It sends that information, either newbid or accept, in a message to site 1. When site 1 receives that message, it decides whether it wants to accept that bid or make a new offer (at a higher offering price). It then sends that information in a message to site 2. The bidding continues, sending messages back and forth, until one of the sites, sa decides to accept a bid or offer and sends that information in a message to the other site, sb. After sending that accept message, sa exits the process, and after receiving the accept message, sb also exits the process. What will be an ideal response?
