[jboss-as7-dev] Attribute meta-data: max-length

[Brian Stansberry]

I somewhat regret using ModelType as the type for the "type" metadata in 
the resource/operations descriptions. The descriptions are a higher 
level construct than DMR itself and the meaning of the metadata is 
somewhat different from the meaning of ModelNode.getType(). Using the 
same thing for both leads to a temptation to push stuff into DMR that 
doesn't belong there.

A new ModelType will create wire format issues. For us to consider that, 
the new type would need to be solving some problem intrisic to DMR 
itself, not a problem that exists at a higher level.
