0. Observation
Logical Container	ClinicalDocument (CDA Class)
Validation	Instance of this type are validated by templateId
XML Format	In the XML format, this property has the namespace `urn:hl7-org:v3`.
Invariants	should-text-ref-value: SHOULD contain text/reference/@value (`text.reference.value.exists()`) should-author: SHOULD contain author (`author.exists()`)
2. Observation.templateId

38. Observation.value.qualifier
Short	The observation/value and all the qualifiers together (often referred to as a post-coordinated expression) make up one concept. Qualifiers constrain the meaning of the primary code, and cannot negate it or change its meaning. Qualifiers can only be used according to well-defined rules of post-coordination and only if the underlying code system defines the use of such qualifiers or if there is a third code system that specifies how other code systems may be combined. In cases where SNOMED CT does not have a precoordinated code that would be appropriate for the problem list, concept post coordination may be used in CDA following the principles outlined in HL7 Version 3 Implementation Guide: TermInfo - Using SNOMED CT in CDA R2 Models, Release 1 using the V3 CD Data type 1 style.

52. Observation.value.qualifier
Definition	Specifies additional codes that increase the specificity of the the primary code.
Short	The observation/value and all the qualifiers together (often referred to as a post-coordinated expression) make up one concept. Qualifiers constrain the meaning of the primary code, and cannot negate it or change its meaning. Qualifiers can only be used according to well-defined rules of post-coordination and only if the underlying code system defines the use of such qualifiers or if there is a third code system that specifies how other code systems may be combined. In cases where SNOMED CT does not have a precoordinated code that would be appropriate for the problem list, concept post coordination may be used in CDA following the principles outlined in HL7 Version 3 Implementation Guide: TermInfo - Using SNOMED CT in CDA R2 Models, Release 1 using the V3 CD Data type 1 style. This is shown in the sample XML.
