HL7 FHIR® Implementation Guide: Breast Cancer Data, Release 1 - US Realm (Draft for Comment)
This page is part of the Breast Cancer Data Logical Models and FHIR Profiles (v0.1.0: STU 1 Draft) based on FHIR R3. . For a full list of available versions, see the Directory of published versions 
Definitions for shr-core-Range.
| Range | |
| Definition | An interval defined by a quantitative upper and/or lower bound. One of the two bounds must be specified, and the lower bound must be less than the upper bound. When Quantities are specified, the units of measure must be the same. |
| Control | 0..* This element is affected by the following invariants: ele-1 |
| Comments | The stated low and high value are assumed to have arbitrarily high precision when it comes to determining which values are in the range. I.e. 1.99 is not in the range 2 -> 3. |
| Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() | (children().count() > id.count())) rng-2: If present, low SHALL have a lower value than high (: low.empty() or high.empty() or (low <= high)) |
| Range.id | |
| Definition | unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. |
| Control | 0..1 |
| Type | string |
| Range.extension | |
| Definition | May be used to represent additional information that is not part of the basic definition of the element. In order to make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. |
| Control | 0..* |
| Type | Extension |
| Alternate Names | extensions, user content |
| Comments | There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone. |
| Range.low | |
| Definition | The low limit. The boundary is inclusive. |
| Control | 0..1 This element is affected by the following invariants: rng-2 |
| Type | Quantity(SimpleQuantity) |
| Comments | If the low element is missing, the low boundary is not known. |
| Range.high | |
| Definition | The high limit. The boundary is inclusive. |
| Control | 0..1 This element is affected by the following invariants: rng-2 |
| Type | Quantity(SimpleQuantity) |
| Comments | If the high element is missing, the high boundary is not known. |
