No easy way to acquire node name from JBoss Transaction SPI

There's no good way to get the node identifier string for the local transaction environment using the integration SPIs. I have to use com.arjuna.ats.arjuna.common.CoreEnvironmentBean#getNodeIdentifier which brings in narayana-jta to make this work.

It would be nice if this could be gotten from the TransactionManager or perhaps the ExtendedJBossXATerminator.
