RE: [wsbpel] Parallel & Deterministic Compensation Behavior

According to latest spec and this PPT, the default compensation handler
determines the compensation order by using the scope completion time.
http://www.oasis-open.org/committees/download.php/4449/Default%20Compensatio
n%20Order.ppt

<scope name=a>
  <flow>
    <scope name=AA/>
    <scope name=AB/>
  </flow>
</scope>

In the above case, the compensation order depends upon how the scopes gets
completed.

if "AA" completed before "AB" (completion order AA,AB). then the
compensation order would be "AB", "AA"

if "AB" completed before "AA" (completion order AB,AA). then the
compensation order would be "AA","AB"
