Definitions for the IVL-TS logical model.
Guidance on how to interpret the contents of this table can be found here.
| 1. IVL_TS | |
| Control | 1..* |
| XML Representation | In the XML format, this property has the namespace urn:hl7-org:v3. |
| 2. IVL_TS.low | |
| Definition | This is the low limit of the interval. |
| Control | 0..1 |
| Type | http://hl7.org/fhir/cda/StructureDefinition/TS |
| 3. IVL_TS.high | |
| Definition | This is the high limit of the interval. |
| Control | 0..1 |
| Type | http://hl7.org/fhir/cda/StructureDefinition/TS |
| 4. 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/fhir/cda/StructureDefinition/PQ |
| 5. 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/fhir/cda/StructureDefinition/TS |
Guidance on how to interpret the contents of this table can be found here.
| 1. 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. |
| Control | 10..* |
| XML Representation | In the XML format, this property has the namespace urn:hl7-org:v3. |
| Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) |
| 2. IVL_TS.low | |
| Definition | This is the low limit of the interval. |
| Control | 0..1 |
| Type | http://hl7.org/fhir/cda/StructureDefinition/TS |

| XML Representation | In the XML format, this property has the namespace urn:hl7-org:v3. |
| 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 NullFlavor |
| Type | code |
| XML Representation | In the XML format, this property is represented as an attribute. |

| Control | 0..1 |
| Type | dateTime |
| XML Representation | In the XML format, this property is represented as an attribute. |
| 4. IVL_TS.inclusive | |
| Definition | Specifies whether the limit is included in the interval (interval is closed) or excluded from the interval (interval is open). |
| Control | 0..1 |
| Type | boolean |
| XML Representation | In the XML format, this property is represented as an attribute. |
| 5. 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 |
| Type | code |
