We have patches for xa support pending, but have not committed them yet. 
Our 2PC support doesn't allow a full XA implementation because full XA 
allows multiple transactions to run in parallel on the same resource and 
allows other threads to join an already running transaction.  The 
question is whether application servers and transaction managers do 
this by default and whether it can be disabled.  Initial research shows 
our support may be good enough for practical purposes.
