SBM configuration should have its own schema[1]. Not sure what effect 
that will have on boot time -- maybe good because the MC isn't dealing 
with a bunch of beans it doesn't really need to know about; maybe bad as 
another new set of xml parsing overhead is added.

Also relevant to the jbossweb-standalone numbers (but not too minimal) 
is SBM is doing that XSL transform on server.xml. There's a JIRA to get 
rid of that, although I'm not too happy about using system properties to 
pass these values. We do it elsewhere though.
