This template is used to specify an security observation associated with an
          information type specified in the privacy consent document or information instance that
          appears in a CDA document. A security observation is an abstract template intended to
          specialized for use to indicate a security classification, control, category, or integrity

  1. SHALL contain exactly one [1..1] templateId ( CONF-CD-21 ) such that it
    1. SHALL contain exactly one [1..1] @root="2.16.840.1.113883.3.445.21"
  2. SHALL contain exactly one [1..1] @moodCode="EVN" Event (CodeSystem: 2.16.840.1.113883.5.1001 HL7ActMood) (CONF:16841)
    • A security observation specifies a field in a security label rather than a typical
                  clinical observation. It provides a way of expressing privacy metadata associated with
                  specific clinical statements included in a document section.

  3. SHALL contain exactly one [1..1] code (CONF:16837), where the @code SHALL be selected from (CodeSystem: 2.16.840.1.113883.1.11.20457 SecurityObservationTypeCodeSystem) (CONF:16838)
    • The code identifies the observation as a security observation using a static
                  terminology binding.

  4. SHALL contain exactly one [1..1] value with @xsi:type="CE" (CONF:16839), where the @code SHALL be selected from (CodeSystem: 2.16.840.1.113883.5.1063 SecurityObservationValueCodeSystem) (CONF:16840)
    • The value specifies the security observation value that may be further constrained
                  for various subclasses/specializations.
