DICOM-20150324: Initial publication, derived from template originally published in DIR r1-2009, revised in Consolidated CDA r1-2011 as 2.16.840.1.113883.10.20.6.2.14. This derivation includes Units of Measure specified with DICOM value set for UCUM (CID 82 “Measurement Unit”), equivalent to C-CDA specified value set (UCUM Units of Measure (case sensitive) 2.16.840.1.113883.11.12839); addition of optional interpretationCode and actionable priority |

The Observation entry SHOULD include a text/reference element, whose value attribute (not to be confused with the value element of the Observation class) SHALL begin with a '#' and SHALL point to its corresponding narrative in the parent section (using the approach defined in CDA Release 2, section 4.3.5.1). See Section 9.1.1.1.
