Definition	Relates an Observation to the ObservationRange class, where the expected range of values for a particular observation can be specified.

In other words, to represent two distinct target populations, two `referenceRange` elements would be used.
Short	Provides guide for interpretation
Comments	Most observations only have one generic reference range. Systems MAY choose to restrict to only supplying the relevant reference range based on knowledge about the patient (e.g., specific to the patient's age, gender, weight and other factors), but this might not be possible or appropriate. Whenever more than one reference range is supplied, the differences between them SHOULD be provided in the reference range and/or age properties.

Slice Name	status
Short	entryRelationship
Comments	MAY contain zero or one [0..1] entryRelationship (CONF:1098-16333) such that it
Control	0..1
Type	http://hl7.org/cda/stds/core/StructureDefinition/EntryRelationship
282. Observation.entryRelationship:status.nullFlavor
Definition	If a value is an exceptional value (NULL-value), this specifies in what way and why proper information is missing.
Control	0..1
Binding	The codes SHALL be taken from CDANullFlavor (required to `http://hl7.org/cda/stds/core/ValueSet/CDANullFlavor`)
Type	code(cs: Coded Simple Value)
Primitive Value	This primitive element may be present, or absent, or replaced by an extension
XML Format	In the XML format, this property is represented as an attribute.
Label	Exceptional Value Detail
284. Observation.entryRelationship:status.realmCode
Definition	When valued in an instance, this attribute signals the imposition of realm-specific constraints. The value of this attribute identifies the realm in question
Control	0..*
Type	http://hl7.org/cda/stds/core/StructureDefinition/CS
286. Observation.entryRelationship:status.typeId
Definition	When valued in an instance, this attribute signals the imposition of constraints defined in an HL7-specified message type. This might be a common type (also known as CMET in the messaging communication environment), or content included within a wrapper. The value of this attribute provides a unique identifier for the type in question.
Control	0..1
Type	http://hl7.org/cda/stds/core/StructureDefinition/II
Invariants	II-1: An II instance must have either a root or an nullFlavor. (`root.exists() or nullFlavor.exists()`)

XML Format	In the XML format, this property is represented as an attribute.
Label	Exceptional Value Detail
290. Observation.entryRelationship:status.typeId.assigningAuthorityName
Definition	A human readable name or mnemonic for the assigning authority. The Assigning Authority Name has no computational value. 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.

454. Observation.entryRelationship:criticality.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.
