NIEM Adapters

I verified with Lizzie DeYoung that portions of an external standard can be referenced in a NIEM adapter.  The example below is from the Geo4NIEM adapter, which references the GML Envelope element.  It is important to note that the Envelope  element is globally scoped and not a locally scoped element.
