If a fault handler has completed without any unhandled fault then a check for orphaned IMA's MUST be made. If any orphaned IMA is detected then a new bpel:missingReply is thrown to the parent scope (similar to throwing or rethrowing other faults from a fault handler). The newly thrown bpel:missingReply fault MUST encompass all orphaned IMA's, and they are no longer considered orphaned. However, if the fault handler is handling a bpel:missingReply fault and no new IMA's were created and left open by the fault handler, a new bpel:missingReply fault MUST NOT be generated or thrown.
