Constraints

Id Grade Path(s) Description Expression
cnl-0 warning StructureDefinition Name should be usable as an identifier for the module by machine processing applications such as code generation name.exists() implies name.matches('^[A-Z]([A-Za-z0-9_]){1,254}$')
cnl-1 warning StructureDefinition.url URL should not contain | or # - these characters make processing canonical references problematic exists() implies matches('^[^|# ]+$')
ele-1 error StructureDefinition.implicitRules, StructureDefinition.extension, StructureDefinition.extension:stringency, StructureDefinition.modifierExtension, StructureDefinition.url, StructureDefinition.name, StructureDefinition.status, StructureDefinition.kind, StructureDefinition.abstract, StructureDefinition.type, StructureDefinition.baseDefinition, StructureDefinition.derivation, StructureDefinition.snapshot, StructureDefinition.snapshot.modifierExtension, StructureDefinition.snapshot.element All FHIR elements must have a @value or children hasValue() or (children().count() > id.count())
ext-1 error StructureDefinition.extension, StructureDefinition.extension:stringency, StructureDefinition.modifierExtension, StructureDefinition.snapshot.modifierExtension Must have either extensions or value[x], not both extension.exists() != value.exists()
sdf-1 error StructureDefinition Element paths must be unique unless the structure is a constraint derivation = 'constraint' or snapshot.element.select(path).isDistinct()
sdf-15a error StructureDefinition If the first element in a differential has no "." in the path and it's not a logical model, it has no type
Requirements:

No Type on the root element (differential)

 (kind!='logical' and differential.element.first().path.contains('.').not()) implies differential.element.first().type.empty()
sdf-3 error StructureDefinition.snapshot Each element definition in a snapshot must have a formal definition and cardinalities, unless model is a logical model %resource.kind = 'logical' or element.all(definition.exists() and min.exists() and max.exists())
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())
sdf-6 error StructureDefinition A structure must have either a differential, or a snapshot (or both) snapshot.exists() or differential.exists()
sdf-8 error StructureDefinition.snapshot All snapshot elements must start with the StructureDefinition's specified type for non-logical models, or with the same type name for logical models (%resource.kind = 'logical' or element.first().path = %resource.type) and element.tail().all(path.startsWith(%resource.snapshot.element.first().path&'.'))
sdf-9 error StructureDefinition In any snapshot or differential, no label, code or requirements on 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-10 error StructureDefinition.snapshot.element provide either a binding reference or a description (or both)
Requirements:

binding is required

 binding.empty() or binding.valueSet.exists() or binding.description.exists()
sdf-11 error StructureDefinition If there's a type, its content must match the path name in the first element of a snapshot
Requirements:

Ensure that the type is not inconsistent with the other information in the structure

 kind != 'logical' implies snapshot.empty() or snapshot.element.first().path = type
sdf-14 error StructureDefinition All element definitions must have an id
Requirements:

elements have id

 snapshot.element.all(id.exists()) and differential.element.all(id.exists())
sdf-15 error StructureDefinition The first element in a snapshot has no type unless model is a logical model.
Requirements:

No Type on the root element (snapshot)

 kind!='logical' implies snapshot.element.first().type.empty()
sdf-16 error StructureDefinition All element definitions must have unique ids (snapshot)
Requirements:

element ids need to be unique

 snapshot.element.all(id.exists()) and snapshot.element.id.trace('ids').isDistinct()
sdf-17 error StructureDefinition All element definitions must have unique ids (diff)
Requirements:

element ids need to be unique

 differential.element.all(id.exists()) and differential.element.id.trace('ids').isDistinct()
sdf-18 error StructureDefinition Context Invariants can only be used for extensions
Requirements:

contextInvariant

 contextInvariant.exists() implies type = 'Extension'
sdf-19 error StructureDefinition FHIR Specification models only use FHIR defined types
Requirements:

custom types only in logical models

 url.startsWith('http://hl7.org/fhir/StructureDefinition') implies (differential | snapshot).element.type.code.all(matches('^[a-zA-Z0-9]+$') or matches('^http:\\/\\/hl7\\.org\\/fhirpath\\/System\\.[A-Z][A-Za-z]+$'))
sdf-21 error StructureDefinition Default values can only be specified on specializations
Requirements:

no default values on data types or resources

 differential.element.defaultValue.exists() implies (derivation = 'specialization')
sdf-22 error StructureDefinition FHIR Specification models never have default values
Requirements:

no default values on data types or resources

 url.startsWith('http://hl7.org/fhir/StructureDefinition') implies (snapshot.element.defaultValue.empty() and differential.element.defaultValue.empty())
sdf-23 error StructureDefinition No slice name on root
Requirements:

no sliceName on root

 (snapshot | differential).element.all(path.contains('.').not() implies sliceName.empty())
sdf-24 error StructureDefinition.snapshot For CodeableReference elements, target profiles must be listed on the CodeableReference, not the CodeableReference.reference element.where(type.where(code='Reference').exists() and path.endsWith('.reference') and type.targetProfile.exists() and (path.substring(0,$this.path.length()-10) in %context.element.where(type.where(code='CodeableReference').exists()).path)).exists().not()
sdf-25 error StructureDefinition.snapshot For CodeableReference elements, bindings must be listed on the CodeableReference, not the CodeableReference.concept element.where(type.where(code='CodeableConcept').exists() and path.endsWith('.concept') and binding.exists() and (path.substring(0,$this.path.length()-8) in %context.element.where(type.where(code='CodeableReference').exists()).path)).exists().not()
sdf-26 best practice StructureDefinition.snapshot The root element of a profile should not have mustSupport = true $this.where(element[0].mustSupport='true').exists().not()
sdf-27 error StructureDefinition If there's a base definition, there must be a derivation baseDefinition.exists() implies derivation.exists()
sdf-28 error StructureDefinition.snapshot.element If there are no discriminators, there must be a definition slicing.exists().not() or (slicing.discriminator.exists() or slicing.description.exists())
sdf-29 warning StructureDefinition Elements in Resources must have a min cardinality or 0 or 1 and a max cardinality of 1 or * ((kind in 'resource' | 'complex-type') and (derivation = 'specialization')) implies differential.element.where((min != 0 and min != 1) or (max != '1' and max != '*')).empty()
sdf-8b error StructureDefinition.snapshot All snapshot elements must have a base definition element.all(base.exists())

sdf-10 error StructureDefinition.snapshot.element provide either a binding reference or a description (or both)
Requirements:

binding is required

 binding.empty() or binding.valueSet.exists() or binding.description.exists()
sdf-11 error StructureDefinition If there's a type, its content must match the path name in the first element of a snapshot
Requirements:

Ensure that the type is not inconsistent with the other information in the structure

 kind != 'logical' implies snapshot.empty() or snapshot.element.first().path = type
sdf-14 error StructureDefinition All element definitions must have an id
Requirements:

elements have id

 snapshot.element.all(id.exists()) and differential.element.all(id.exists())
sdf-15 error StructureDefinition The first element in a snapshot has no type unless model is a logical model.
Requirements:

No Type on the root element (snapshot)

 kind!='logical' implies snapshot.element.first().type.empty()
sdf-16 error StructureDefinition All element definitions must have unique ids (snapshot)
Requirements:

element ids need to be unique

 snapshot.element.all(id.exists()) and snapshot.element.id.trace('ids').isDistinct()
sdf-17 error StructureDefinition All element definitions must have unique ids (diff)
Requirements:

element ids need to be unique

 differential.element.all(id.exists()) and differential.element.id.trace('ids').isDistinct()
sdf-18 error StructureDefinition Context Invariants can only be used for extensions
Requirements:

contextInvariant

 contextInvariant.exists() implies type = 'Extension'
sdf-19 error StructureDefinition FHIR Specification models only use FHIR defined types
Requirements:

custom types only in logical models

 url.startsWith('http://hl7.org/fhir/StructureDefinition') implies (differential | snapshot).element.type.code.all(matches('^[a-zA-Z0-9]+$') or matches('^http:\\/\\/hl7\\.org\\/fhirpath\\/System\\.[A-Z][A-Za-z]+$'))
sdf-21 error StructureDefinition Default values can only be specified on specializations
Requirements:

no default values on data types or resources

 differential.element.defaultValue.exists() implies (derivation = 'specialization')
sdf-22 error StructureDefinition FHIR Specification models never have default values
Requirements:

no default values on data types or resources

 url.startsWith('http://hl7.org/fhir/StructureDefinition') implies (snapshot.element.defaultValue.empty() and differential.element.defaultValue.empty())
sdf-23 error StructureDefinition No slice name on root
Requirements:

no sliceName on root

 (snapshot | differential).element.all(path.contains('.').not() implies sliceName.empty())
sdf-24 error StructureDefinition.snapshot For CodeableReference elements, target profiles must be listed on the CodeableReference, not the CodeableReference.reference element.where(type.where(code='Reference').exists() and path.endsWith('.reference') and type.targetProfile.exists() and (path.substring(0,$this.path.length()-10) in %context.element.where(type.where(code='CodeableReference').exists()).path)).exists().not()
sdf-25 error StructureDefinition.snapshot For CodeableReference elements, bindings must be listed on the CodeableReference, not the CodeableReference.concept element.where(type.where(code='CodeableConcept').exists() and path.endsWith('.concept') and binding.exists() and (path.substring(0,$this.path.length()-8) in %context.element.where(type.where(code='CodeableReference').exists()).path)).exists().not()
sdf-26 best practice StructureDefinition.snapshot The root element of a profile should not have mustSupport = true $this.where(element[0].mustSupport='true').exists().not()
sdf-27 error StructureDefinition If there's a base definition, there must be a derivation baseDefinition.exists() implies derivation.exists()
sdf-28 error StructureDefinition.snapshot.element If there are no discriminators, there must be a definition slicing.exists().not() or (slicing.discriminator.exists() or slicing.description.exists())
sdf-29 warning StructureDefinition Elements in Resources must have a min cardinality or 0 or 1 and a max cardinality of 1 or * ((kind in 'resource' | 'complex-type') and (derivation = 'specialization')) implies differential.element.where((min != 0 and min != 1) or (max != '1' and max != '*')).empty()
sdf-8b error StructureDefinition.snapshot All snapshot elements must have a base definition element.all(base.exists())
