| Realm | uv |
| Authority | hl7 |
| Description | STU3: `DeviceMetric.identifier` additional types (Identifier) additional types from child elements (assigner, period, system, type, use, value) |
| Purpose | This extension is part of the cross-version definitions generated to enable use of the element `DeviceMetric.identifier` as defined in FHIR STU3 in FHIR R4B. The source element is defined as: `DeviceMetric.identifier` 1..1 `Identifier` Across FHIR versions, the element set has been mapped as: * STU3: `DeviceMetric.identifier` 1..1 `Identifier` * R4: `DeviceMetric.identifier` 0..* `Identifier` * R4B: `DeviceMetric.identifier` 0..* `Identifier` Following are the generation technical comments: Element `DeviceMetric.identifier` is mapped to FHIR R4B element `DeviceMetric.identifier` as `RelatedTo`. The mappings for `DeviceMetric.identifier` do not cover the following types: Identifier. The mappings for `DeviceMetric.identifier` do not cover the following types based on type expansion: assigner, period, system, type, use, value. |
