| Realm | uv |
| Authority | hl7 |
| Description | R5: `NutritionIntake.occurrence[x]` (new:dateTime, Period) |
| Purpose | This extension is part of the cross-version definitions generated to enable use of the element `NutritionIntake.occurrence[x]` as defined in FHIR R5 in FHIR R4. The source element is defined as: `NutritionIntake.occurrence[x]` 0..1 `dateTime, Period` Across FHIR versions, the element set has been mapped as: * R5 `NutritionIntake.occurrence[x]` 0..1 `dateTime, Period` Following are the generation technical comments: Element `NutritionIntake.occurrence[x]` is not mapped to FHIR R4, since FHIR R5 `NutritionIntake` is not mapped. Element `NutritionIntake.occurrence[x]` has no mapping targets in FHIR R4. Typically, this is because the element has been added (is a new element). |
