purpose:
  v: This extension is part of the cross-version definitions generated to enable use of the element `SubstanceReferenceInformation.geneElement` as defined in FHIR R4 in FHIR STU3. The source element is defined as: `SubstanceReferenceInformation.geneElement` 0..* `BackboneElement` Following are the generation technical comments: Element `SubstanceReferenceInformation.geneElement` is not mapped to FHIR STU3, since FHIR R4 `SubstanceReferenceInformation` is not mapped. Element `SubstanceReferenceInformation.geneElement` has no mapping targets in FHIR STU3. Typically, this is because the element has been added (is a new element).

  v: Element `SubstanceReferenceInformation.geneElement.type` is part of an existing definition because parent element `SubstanceReferenceInformation.geneElement` requires a cross-version extension. Element `SubstanceReferenceInformation.geneElement.type` is not mapped to FHIR STU3, since FHIR R4 `SubstanceReferenceInformation` is not mapped. Element `SubstanceReferenceInformation.geneElement.type` has no mapping targets in FHIR STU3. Typically, this is because the element has been added (is a new element).
