Is it possible to have datasource aliases in JBoss? E.g. instead of:

<?xml version="1.0" encoding="UTF-8"?>
<datasources>
   <local-tx-datasource>
       <jndi-name>ds-1</jndi-name>
       <connection-url>jdbc:abc</connection-url>
       <user-name>def</user-name>
       <password>ghi</password>
       ...
   </local-tx-datasource>
</datasources>

<?xml version="1.0" encoding="UTF-8"?>
<datasources>
   <local-tx-datasource>
       <jndi-name>ds-2</jndi-name>
       <connection-url>jdbc:abc</connection-url>
       <user-name>def</user-name>
       <password>ghi</password>
       ...
   </local-tx-datasource>
</datasources>

have something like:

<?xml version="1.0" encoding="UTF-8"?>
<datasources>
   <local-tx-datasource>
       <jndi-name>ds-1</jndi-name>
       <connection-url>jdbc:abc</connection-url>
       <user-name>def</user-name>
       <password>ghi</password>
       ...
   </local-tx-datasource>
</datasources>

<?xml version="1.0" encoding="UTF-8"?>
<datasources>
   <local-tx-datasource>
       <jndi-name>ds-2</jndi-name>
        <alias>ds-1</alias>
   </local-tx-datasource>
</datasources>

or something in that fashion. This would allow for:
- Not having duplicate information (e.g. connection URLs, usernames, passwords, etc.)
- Supporting legacy or just other applications that require the same logical connection, but use different data-source names
- Easy testing of multiple data-sources on one database (i.e. on the same data, even though the apps were designed to use physically different DBs)

Any ideas appreciated. Also - as a general thing - is it possible to have aliases for other things (e.g. MQ topic aliases, etc.).
