Hmmmm, not sure I understand what you mean by declarative configurations 
here. I'd imagine AS, apart from being able to provide it's own 
Transport programatically, it could do do something like this in the 
Infinispan configurations running on AS:

<transport transportClass="org.jboss.as.infinispan.JGroupsTransport"
...

And within that implementation, lookup the JGroups transport in AS and 
return what the Transport interface mandates.

The above example is what I understand by declarative.
