MDMI2 — Merged with issue 40

The resolution of this issue is correlated to issue # 41 because the issue and the resolution of both issues have dependencies.

Issue: The name of the Business Element in the example beginning on the bottom of page 52 was VitalSignObservationActionFocus. Based on the work of the FTF, this name is not appropriate and should not be used. The name is inappropriate because Vital Sign Observation term as the ContentConcept property (formerly the StatementConcept Property) should be ObservationActivity. The name is also not appropriate because the term for the DataElementConcept Property, formerly ActionFocus, should be ContextFocus based on advice of the SMEs in the FTF.
