Error conditions are handled as follows:

• If the remote system does not support transactions and the WS-AT Assertion/transaction context call has must create transaction semantics, a TPESYSTEM error is returned to the client.
• Errors generated remotely are returned to the Oracle Tuxedo client in the same manner as regular, non-transactional calls. The fault Reason and Detail fields returned describe the nature of the failure (which is environment dependent).
