Extension: targetElement

FHIR Infrastructure Work Group

Maturity Level: 1

Trial Use

Use Context: Any

Official URL: `http://hl7.org/fhir/StructureDefinition/targetElement`				Version: 5.0.0-snapshot3
draft as of 2015-02-28				Computable Name: targetElement
Flags: Non-Modifier				OID: TBD

Context of Use: Use on Element ID Reference or Element ID canonical

Definition

Indicates that the reference has a particular focus in the target resource, a particular element of interest, identified by it's element id.

Comment:

This behaves similar to a '#' element on a URL, but is more wide-open than how '#' is used in Reference.reference where it is limited to pointing only to contained resources (and where the contained resource must be of the appropriate resource type for the reference). This extension allows referring to any Element (not necessarily a resource) within the target resource provided that it has a populated 'id' element. When there is no id on the telement of interest, the extension http://hl7.org/fhir/StructureDefinition/targetPath can be used.
