An object that provides support for distributed
transactions.  An XAConnection object  may be enlisted
in a distributed transaction by means of an XAResource object.
A transaction manager, usually part of a middle tier server, manages an
XAConnection object through the XAResource object.


An application programmer does not use this interface directly; rather,
it is used by a transaction manager working in the middle tier server.
