[jboss-as7-dev] Expressions

[Brian Stansberry]

There are two pieces of metadata that control this. They apply either to 
an attribute or to an operation parameter.

1) "type" --  A ModelType -- The basic type of the attribute/parameter. 
This will *never* be ModelType.EXPRESSION.

2) "expressions-allowed" -- a boolean -- If present with value "true" 
indicates that ModelType.EXPRESSION is also legal for this 
attribute/parameter. Otherwise, only the basic type is legal.

http://community.jboss.org/docs/DOC-16317 includes a bit more verbose 
details on these.
