We could say that defining a server as part of a cluster means that additional capabilities are added beyond what's in the profile. But then we are dividing the definition of a profile into two places. Also, exactly what capabilities should be added if a server is in a cluster is unclear.

To me our previous definition of profile focused much more on internal implementation details (how to build a server with ejb3 (which jars etc)). When I look at the domain model I am looking at it from a configuration standpoint. Specifying things like "jndi should be clustered on port blah blah blah". There should be a thread pool with X threads, etc 

The part of our existing profile discussion I was thinking of was what's shown here:  http://community.jboss.org/docs/DOC-14742 http://community.jboss.org/docs/DOC-14742. Basically a fairly compact listing of required capabilities, an indication of where a deploy directory is (which could perhaps be defaulted). Then add stuff like jdbc-resources, jms-resources, threads, etc. That's pretty end-user-oriented; the heavy implementation detail stuff is in  http://community.jboss.org/docs/DOC-14743 http://community.jboss.org/docs/DOC-14743.

If we didn't need the required capabilities bit (e.g. could infer them from the rest of domain.xml content), that's nice. But I don't know if we can do that, not if we allow a deploy dir with contents not fully specified in domain.xml.
