Constraints

Id	Grade	Path(s)	Details	Requirements
cnl-0	warning	Questionnaire	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}$')
cnl-1	warning	Questionnaire.url	Warning Questionnaire.url URL should not contain | or # - these characters make processing canonical references problematic : exists() implies matches('^[^|# ]+$')

dom-5	error	Questionnaire	If a resource is contained in another resource, it SHALL NOT have a security label : contained.meta.security.empty()
dom-6	best practice	Questionnaire	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()
que-0	warning	Questionnaire	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}')
que-1	error	Questionnaire.item	Group items must have nested items, display items cannot have nested items : (type='group' implies item.empty().not()) and (type.trace('type')='display' implies item.trace('item').empty())
que-1a	error	Questionnaire.item	Group items must have nested items when Questionanire is complete : (type='group' and %resource.status='complete') implies item.empty().not()
que-1b	warning	Questionnaire.item	Groups should have items : type='group' implies item.empty().not()
que-1c	error	Questionnaire.item	Display items cannot have child items : type='display' implies item.empty()

que-3	error	Questionnaire.item	Display items cannot have a "code" asserted : type!='display' or code.empty()
que-4	error	Questionnaire.item	A question cannot have both answerOption and answerValueSet : answerOption.empty() or answerValueSet.empty()
que-5	error	Questionnaire.item	Only 'choice' and 'open-choice' items can have answerValueSet : (type ='choice' or type = 'open-choice' or type = 'decimal' or type = 'integer' or type = 'date' or type = 'dateTime' or type = 'time' or type = 'string' or type = 'quantity') or (answerValueSet.empty() and answerOption.empty())
que-6	error	Questionnaire.item	Required and repeat aren't permitted for display items : type!='display' or (required.empty() and repeats.empty())
que-7	error	Questionnaire.item.enableWhen	If the operator is 'exists', the value must be a boolean : operator = 'exists' implies (answer is Boolean)
que-8	error	Questionnaire.item	Initial values can't be specified for groups or display items : (type!='group' and type!='display') or initial.empty()
que-9	error	Questionnaire.item	Read-only can't be specified for "display" items : type!='display' or readOnly.empty()
que-10	error	Questionnaire.item	Maximum length can only be declared for simple question types : (type in ('boolean' | 'decimal' | 'integer' | 'string' | 'text' | 'url' | 'open-choice')) or maxLength.empty()
que-11	error	Questionnaire.item	If one or more answerOption is present, initial[x] must be missing : answerOption.empty() or initial.empty()
que-12	error	Questionnaire.item	If there are more than one enableWhen, enableBehavior must be specified : enableWhen.count() > 2 implies enableBehavior.exists()
que-13	error	Questionnaire.item	Can only have multiple initial values for repeating items : repeats=true or initial.count() <= 1
que-14	warning	Questionnaire.item	Can only have answerConstraint if answerOption, answerValueSet, or answerExpression are present. (This is a warning because other extensions may serve the same purpose) : extension('http://hl7.org/fhir/5.0/StructureDefinition/extension-Questionnaire.item.answerConstraint').exists() implies answerOption.exists() or answerValueSet.exists() or extension('http://hl7.org/fhir/uv/sdc/StructureDefinition/sdc-questionnaire-answerExpression').exists()
que-15	error	Questionnaire.item.linkId	Link ids must be 255 characters or less : $this.length() <= 255
sdc-1	error	Questionnaire.item	An item cannot have an answerExpression if answerOption or answerValueSet is already present. : extension('http://hl7.org/fhir/uv/sdc/StructureDefinition/sdc-questionnaire-answerExpression').empty().not() implies (answerOption.empty() and answerValueSet.empty())
sdc-2	error	Questionnaire	If version is present, versionAlgorithm must be present. : version.exists() implies extension.where(url='http://hl7.org/fhir/5.0/StructureDefinition/extension-Questionnaire.versionAlgorithm[x]').exists()
sdc-3	best practice	Questionnaire	Semver is the preferred version algorithm - package machinery doesn't work well with artifacts using alternate versioning schemes : extension.where(url='http://hl7.org/fhir/5.0/StructureDefinition/extension-Questionnaire.versionAlgorithm[x]').all(value.ofType(Coding).where(system='http://hl7.org/fhir/version-algorithm' and code='semver').exists())
