dom-3	error	StructureDefinition	If the resource is contained in another resource, it SHALL be referred to from elsewhere in the resource	contained.where(('#'+id in %resource.descendants().reference).not()).empty()
dom-4	error	StructureDefinition	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()
sdf-1	error	StructureDefinition	Element paths must be unique unless the structure is a constraint	derivation = 'constraint' or snapshot.element.select(path).isDistinct()
sdf-4	error	StructureDefinition	If the structure is not abstract, then there SHALL be a baseDefinition Requirements: Ensure that the base types are abstract	abstract = true or baseDefinition.exists()
sdf-5	error	StructureDefinition	If the structure defines an extension then the structure must have context information	type != 'Extension' or derivation = 'specialization' or (context.exists() and contextType.exists())
sdf-6	error	StructureDefinition	A structure must have either a differential, or a snapshot (or both)	snapshot.exists() or differential.exists()
sdf-7	error	StructureDefinition	If the structure describes a base Resource or Type, the URL has to start with "http://hl7.org/fhir/StructureDefinition/" and the tail must match the id	(derivation = 'constraint') or (kind = 'logical') or (url = 'http://hl7.org/fhir/StructureDefinition/'+id)
sdf-9	error	StructureDefinition	In any snapshot or differential, no label, code or requirements on the an element without a "." in the path (e.g. the first element) Requirements: Because these 3 fields seem to be have overlapping meaning with the ones in the root of StructureDefinition	children().element.where(path.contains('.').not()).label.empty() and children().element.where(path.contains('.').not()).code.empty() and children().element.where(path.contains('.').not()).requirements.empty()

sdf-18	error	StructureDefinition	Context Invariants can only be used for extensions Requirements: contextInvariant	contextInvariant.exists() implies type = 'Extension'
