Act in DEF Mood
Various challenges with using DEV (or EVN.CRT) mood have been identified. These are detailed here: http://wiki.hl7.org/images/d/d1/EMeasureMNMPresentation_17July2009.pdf
 Document characteristic attributes: Current thinking is to assume that in EVN.CRT mood, no properties are documentation characteristic. Gunther suggests that we may need to split Act.statusCode into an Act.actStatusCode and an Act.recordStatusCode.
 Vocabulary binding: Current thinking is to include a local code, which in the local code system reflects a value set.
