DMN16 — XSD: global context

10.3.2.9.2 says "The global context is a context provided for convenience and 'pre-compilation'. Any number of expressions can be named and represented in a FEEL context m. The syntactic description m of this context can be evaluated once, that is, mapped to the FEEL domain as m, and then re-used to evaluate many expressions." For example, you might want to put a Relation used as a multi-dimensional constant in the global context. Or you might want to put a reusable function definition in the global context. Currently the xsd does not have globals. All expressions are bound to a specific drgElement, not global. The Import element probably needs to be modified to support this also.
