Summary

Defining URL:http://hl7.org/fhir/StructureDefinition/targetElement
Version:5.0.0-cibuild
Name:targetElement
Title:null
Modifier:This extension is not a modifier extension
Status:draft
Definition:Indicates that the reference has a particular focus in the target resource, a particular element of interest, identified by it's element id.
Committee:FHIR Infrastructure Work Group

Status: draft. Extension maintained by: Health Level Seven, Inc. - FHIR Core WG

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.

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