I don't mean to be picky but... XA <> XATMI. They are completely different standards. The XA specification, which is a CAE Specification, is concerned with the communication between the the Resource Manager (i.e. Oracle, Informix) and the Transaction Manager (i.e. TOP END, TUXEDO, ENCINA). The XATMI specification, which is still a snapshot, is as correctly stated above, concerned with the Transaction Manager, application interface.
Alas, we are still waiting for the XATMI specification to reach a more matured stage, where hopefully TP vendors will implement the API, and we can write standard TP applications which will interwork with more than one TP monitor.
The only interoperability, which I am aware of at present, is that TOP END for NCR will/does provide a TUXEDO compatibility layer. But you need to ask NCR for more information about that.
