R4: SubstanceSpecification.structure.isotope.molecularWeight (new:BackboneElement)
This extension is part of the cross-version definitions generated to enable use of the
element SubstanceSpecification.structure.isotope.molecularWeight as defined in FHIR R4
in FHIR STU3.
The source element is defined as:
SubstanceSpecification.structure.isotope.molecularWeight 0..1 BackboneElement
Following are the generation technical comments:
Element SubstanceSpecification.structure.isotope.molecularWeight is part of an existing definition because parent element SubstanceSpecification.structure.isotope requires a cross-version extension.
Element SubstanceSpecification.structure.isotope.molecularWeight is not mapped to FHIR STU3, since FHIR R4 SubstanceSpecification is not mapped.
Element SubstanceSpecification.structure.isotope.molecularWeight has no mapping targets in FHIR STU3. Typically, this is because the element has been added (is a new element).
Creating extension because element SubstanceSpecification.structure.isotope.molecularWeight is a content reference and requires an extesion definition.
