This page is part of the FHIR Core Extensions Registry (v5.3.0-ballot-tc1: Release 5.3) based on FHIR (HL7® FHIR® Standard) v5.0.0. This version is a pre-release. The current official version is 5.2.0. For a full list of available versions, see the Directory of published versions
Official URL: http://hl7.org/fhir/StructureDefinition/preferredValueAlternatives | Version: 5.3.0-ballot-tc1 | |||
Standards status: Trial-use | Maturity Level: 1 | Computable Name: PreferredValueAlternatives |
An extension (or if multiple, a collection of alternative extensions) that SHOULD be used in the event a value element is not present.
This is similar to valueAlternatives, however, unlike valueAlternatives it is not an error if extensions other than those listed in the 'preferredValueAlternatives' are used in place of a value. Like valueAlternatives, this extension is only appropriate on primitive types. It makes no sense if specified on an element where mustHaveValue is true.
Context of Use
This extension may be used on the following element(s)
