Extension: StructureDefinition FHIR Type

FHIR Infrastructure Work Group Maturity Level: 1Trial UseUse Context: Any
Official URL: http://hl7.org/fhir/StructureDefinition/structuredefinition-fhir-type Version: 5.0.0-snapshot3
draft as of 2014-01-31 Computable Name: SDFhirType
Flags: Non-Modifier OID: 2.16.840.1.113883.4.642.5.1013

Context of Use: Use on Element ID ElementDefinition.type

Definition

The FHIR type of a property - used on the value property of a primitive type (for which there is no type in the FHIR typing system), and Element.id, Resource.id, and Extension.url. All of these have a non-FHIR type in thir structure definition, and this specifies the applicable FHIR type.

Comment:

This is in effect, compiler magic for the typing system.
