DescriptionDSTU2: `HealthcareService.publicKey` (new:string)
PurposeThis extension is part of the cross-version definitions generated to enable use of the element `HealthcareService.publicKey` as defined in FHIR DSTU2 in FHIR R4B. The source element is defined as: `HealthcareService.publicKey` 0..1 `string` Across FHIR versions, the element set has been mapped as: * DSTU2: `HealthcareService.publicKey` 0..1 `string` Following are the generation technical comments: Element `HealthcareService.publicKey` has a context of HealthcareService based on following the parent source element upwards and mapping to `HealthcareService`. Element `HealthcareService.publicKey` has no mapping targets in FHIR R4B. Typically, this is because the element has been added (is a new element).
