Status: draft. Extension maintained by: Health Level Seven, Inc. - [WG Name] WG

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.

Context of Use: Use on Element ID ElementDefinition.type
