When I wrote the patch for the backend support, I was not able to find
any open source implementations of X/Open XA-compatible resource
managers or transaction managers, which makes it kind of hard to
implement the API correctly. There was plenty of JDBC XA
implementations, however, so I used that for testing.
If you can find something to test it with, it probably wouldn't be that
hard to write the library.
