Extension: inheritedExtensibleValueSet

FHIR Infrastructure Work Group

Maturity Level: 1

Informative

Use Context: Any

URL for this extension:

http://hl7.org/fhir/StructureDefinition/elementdefinition-inheritedExtensibleValueSet

Status: draft. Extension maintained by: Health Level Seven, Inc. - FHIR Core WG

A reference to an extensible value set specified in a parent profie in order to allow a conformance checking tool to validate that a code not in the extensible value set of the profile is not violating rules defined by parent profile bindings.

Comment:

This extension is only needed where the binding strength is 'extensible', the parents are also 'extensible'. This allows a validator to work around the fact that restricting extensible value sets in child profiles loses constraints out of the parent profiles, (e.g. codes to be used when appropriate).

Context of Use: Use on Element ID ElementDefinition.binding
