--------------------------------------

I'd like to add some more confusion to this "to pad or not to pad" dilemma. ;-) 
Do you consider scenarios when resource managers talk to each other or talk 
back to JBoss? For example, say a transaction spans two databases -- DB2 and 
Oracle. First, JBoss talks to DB2 with unpadded Xid, then JBoss talks to Oracle 
with padded Xid' but Oracle, behind the scenes, talks to DB2. I do not think 
DB2 will be able to match Xid with Xid'.

> Padding should be a JCA option
