      <description
                   value="This clinical statement represents Advance Directive Observation findings (e.g., resuscitation status is Full Code) rather than orders. It should not be considered a legal document or a substitute for the actual Advance Directive document. The related legal documents are referenced using the reference/externalReference element.
    The Advance Directive Observation describes the patients directives, including but not limited to:
     Medications
     Transfer of Care to Hospital
     Treatment
     Procedures
     Intubation and Ventilation
     Diagnostic Tests
     Tests

    The observation/value element contains the detailed patient directive which may be coded or text. For example, a category directive may be antibiotics, and the details would be intravenous antibiotics only.
