Extension: Artifact use context

Official URL: http://hl7.org/fhir/StructureDefinition/artifact-useContext				Version: 5.2.0-ballot
Standards status: Trial-use		Maturity Level: 2	Responsible: HL7 International / Clinical Decision Support	Computable Name: ArtifactUseContext
Other Identifiers: OID:2.16.840.1.113883.4.642.5.1761

The content was developed with a focus and intent of supporting the contexts that are listed. These contexts may be general categories (gender, age, …) or may be references to specific programs (insurance plans, studies, …) and may be used to assist with indexing and searching for appropriate artifact instances.

This extension is defined to support representing artifact metadata on resources that are not already canonical resources that have the corresponding element, and that behave in a definitional way. For example, it would not be appropriate to use this extension on a patient-specific resource such as MedicationRequest or CarePlan.

Constraints

Id	Grade	Path(s)	Details	Requirements
ele-1	error	**ALL** elements	All FHIR elements must have a @value or children : hasValue() or (children().count() > id.count())
