In most cases perhaps not.  But what about config required for JBoss and XA/2PC datasources?  Isn't that config manually required in foo-xa-ds.xml as well as configuring default tx isolation?

<transaction-isolation> - the default transaction isolation of the connection (unspecified means use the default provided by the database):
