2.29.0 BackboneElement

FHIR Infrastructure Work GroupMaturity Level: 5Ballot Status: Normative

Normative Candidate Note: This page is candidate normative content for R4 in the Infrastructure Package. Once normative, it will lose it's Maturity Level, and breaking changes will no longer be made.

The base definition for complex elements defined as part of a resource definition - that is, elements that have children that are defined in the resource. Data Type elements do not use this type, though a few data types specialize it (Timing, Dosage, ElementDefinition). For instance, Patient.contact is an element that is defined as part of the patient resource, so it automatically has the type BackboneElement.

Note that the descendant types of BackboneElement are all declared implicitly as part of the definitions of the resources.
