Definitions for the IVL-TS logical model.

0. IVL_TS
Control	1..*
Logical Container	ClinicalDocument (CDA Class)
XML Format	In the XML format, this property has the namespace `urn:hl7-org:v3`.
Invariants	ivl-ts-center: Center cannot co-exist with low or high (`center.empty() or (low.empty() and high.empty())`)
2. IVL_TS.low
Definition	This is the low limit of the interval.
Control	0..1
Type	http://hl7.org/cda/stds/core/StructureDefinition/IVXB-TS
Label	Low Boundary
4. IVL_TS.center
Definition	The arithmetic mean of the interval (low plus high divided by 2). The purpose of distinguishing the center as a semantic property is for conversions of intervals from and to point values.
Control	0..1
Type	http://hl7.org/cda/stds/core/StructureDefinition/TS
Label	Central Value
6. IVL_TS.width
Definition	The difference between high and low boundary. The purpose of distinguishing a width property is to handle all cases of incomplete information symmetrically. In any interval representation only two of the three properties high, low, and width need to be stated and the third can be derived.
Control	0..1
Type	http://hl7.org/cda/stds/core/StructureDefinition/PQ
Label	Width
8. IVL_TS.high
Definition	This is the high limit of the interval.
Control	0..1
Type	http://hl7.org/cda/stds/core/StructureDefinition/IVXB-TS
Label	High Boundary

Guidance on how to interpret the contents of this table can be found here

0. IVL_TS
Definition	A quantity specifying a point on the axis of natural time. A point in time is most often represented as a calendar expression. Base definition for all types defined in FHIR type system.
Short	Base for all types and resources
Control	10..*
Is Modifier	false
Logical Container	ClinicalDocument (CDA Class)
XML Format	In the XML format, this property has the namespace `urn:hl7-org:v3`.
Invariants	ivl-ts-center: Center cannot co-exist with low or high (`center.empty() or (low.empty() and high.empty())`)
2. IVL_TS.low
Definition	This is the low limit of the interval.
Control	0..1
Type	http://hl7.org/cda/stds/core/StructureDefinition/IVXB-TS
Label	Low Boundary
4. IVL_TS.center
Definition	The arithmetic mean of the interval (low plus high divided by 2). The purpose of distinguishing the center as a semantic property is for conversions of intervals from and to point values.
Control	0..1
Type	http://hl7.org/cda/stds/core/StructureDefinition/TS
Label	Central Value

Label	High Boundary

2. IVL_TS.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
4. IVL_TS.value
Definition	A quantity specifying a point on the axis of natural time. A point in time is most often represented as a calendar expression.
Control	0..1
Type	dateTime(ts: Point in Time)
Primitive Value	This primitive element may be present, or absent, or replaced by an extension
Date Format	YYYYMMDDHHMMSS.UUUU[+\|-ZZzz]
XML Format	In the XML format, this property is represented as an attribute.
6. IVL_TS.operator
Definition	A code specifying whether the set component is included (union) or excluded (set-difference) from the set, or other set operations with the current set component and the set as constructed from the representation stream up to the current point.
Control	0..1
Binding	The codes SHALL be taken from CDASetOperator (required to `http://hl7.org/cda/stds/core/ValueSet/CDASetOperator`)
Type	code(cs: Coded Simple Value)
Primitive Value	This primitive element may be present, or absent, or replaced by an extension
