Provides an alternative value for the element carrying this extension that is the correct value for a particular range of FHIR versions other than the default value. This extension is found in contexts where a definition is applying to more than one version, usually defining extensions, and should only be used in context that clearly document how a cross-version definition is used. While there are no limitations to where this extension can be used, known uses are: StructureDefinition.context, ElementDefinition.type, ElementDefinition.additionalBinding and …
Context of Use
This extension may be used on the following element(s)
 
This extension is primarily to support functionality such as differing FHIRPaths between versions for SearchParameter definitions, SubscriptionTopics, and extension contexts. Authors interested in using this extension for other purposes should check with FHIR Infrastructure about whether their intended use is safe/appropriate.
