Right, and I'm saying the natural way to handle this and leverage the existing xml binding deployers is to: 1. Transform the ds.xml into an xml doc partitioned with namespaces: | <datasources> | <xa-datasource> | <username /> | <password /> | <min-pool-size/> | <max-pool-size/> | <connection-url/> | <xa-datasource-property/> | <xa-datasource> | </datasources> | goes to via a new xsl | <dsxml:datasources> | <dsxml:xa-datasource> | <ns1:username /> | <ns1:password /> | <ns1:connection-url/> | <ns2:min-pool-size/> | <ns2:max-pool-size/> | <ns3:xa-datasource-property/> | <dsxml:xa-datasource> | </dsxml:datasources> | where you have jaxb or jbossxb factories for each of the dsxml, ns1, ns2, ns3 namespaces that produce distinct metadata attachments for each namespace.
