0. Observation
Definition	Defines the basic properties of every data value. This is an abstract type, meaning that no value can be just a data value without belonging to any concrete type. Every concrete type is a specialization of this general abstract DataValue type. Base definition for all types defined in FHIR type system.
Short	Base for all types and resources
Control	10..1*
Is Modifier	false
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-sdtcCategory: SHOULD contain sdtcCategory (`sdtcCategory.exists()`) category-social-history: If category is present, then there shall be a category with code 'social-history'. (`sdtcCategory.empty() or sdtcCategory.exists(code = 'social-history' and codeSystem = 'http://terminology.hl7.org/CodeSystem/observation-category')`) should-value: SHOULD contain value (`value.exists()`) 4515-8555: If Observation/value is a physical quantity (xsi:type="PQ"): This value SHALL contain exactly one [1..1] @unit, which SHOULD be selected from ValueSet UnitsOfMeasureCaseSensitive urn:oid:2.16.840.1.113883.1.11.12839 DYNAMIC.

Short	Who and/or what the observation is about
Comments	One would expect this element to be a cardinality of 1..1. The only circumstance in which the subject can be missing is when the observation is made by a device that does not know the patient. In this case, the observation SHALL be matched to a patient through some context/channel matching technique, and at this point, the observation should be updated. The subject of an Observation may in some cases be a procedure. This supports the regulatory inspection use case where observations are captured during inspections of a procedure that is being performed (independent of any particular patient or whether patient related at all).

The purpose of a Assigning Authority Name is to assist an unaided human interpreter of an II value to interpret the authority. Note: no automated processing must depend on the assigning authority name to be present in any form.

232. Observation.entryRelationship:entryReference.contextConductionInd
Definition	The entryRelationship.contextConductionInd differs from the otherwise common use of this attribute in that in all other cases where this attribute is used, the value is fixed at "true", whereas here the value is defaulted to "true", and can be changed to "false" when referencing an entry in the same document. Setting the context conduction to false when referencing an entry in the same document keeps clear the fact that the referenced object retains its original context.
