dom-3	error	Library	If the resource is contained in another resource, it SHALL be referred to from elsewhere in the resource or SHALL refer to the containing resource : contained.where((('#'+id in (%resource.descendants().reference | %resource.descendants().as(canonical) | %resource.descendants().as(uri) | %resource.descendants().as(url))) or descendants().where(reference = '#').exists() or descendants().where(as(canonical) = '#').exists() or descendants().where(as(canonical) = '#').exists()).not()).trace('unmatched', id).empty()
dom-4	error	Library	If a resource is contained in another resource, it SHALL NOT have a meta.versionId or a meta.lastUpdated : contained.meta.versionId.empty() and contained.meta.lastUpdated.empty()
dom-5	error	Library	If a resource is contained in another resource, it SHALL NOT have a security label : contained.meta.security.empty()
dom-6	best practice	Library	A resource should have narrative for robust management : text.`div`.exists()
ele-1	error	**ALL** elements	All FHIR elements must have a @value or children : hasValue() or (children().count() > id.count())
ext-1	error	**ALL** extensions	Must have either extensions or value[x], not both : extension.exists() != value.exists()
lib-0	warning	Library	Name should be usable as an identifier for the module by machine processing applications such as code generation : name.matches('[A-Z]([A-Za-z0-9_]){0,254}')

Structures

This structure refers to these other structures:

• Shareable CodeSystem (http://hl7.org/fhir/StructureDefinition/shareablecodesystem)
• Shareable Library (http://hl7.org/fhir/StructureDefinition/shareablelibrary)
• Shareable ValueSet (http://hl7.org/fhir/StructureDefinition/shareablevalueset)

Slices

This structure defines the following Slices:

• The element 1 is sliced based on the value of Library.relatedArtifact
• The element 1 is sliced based on the value of Library.content
