0. Extension
Definition	The type of data entry control or structure that should be used to render the item.
Short	E.g. Fly-over, Table, Checkbox, Combo-box, Lookup, etc.
Comments	Different controls may be appropriate for different item types. It is up to the system rendering a questionnaire as to what controls it will support and for which data types. See additional guidance and examples in the SDC implementation guide.
Control	0..1
2. Extension.extension
Control	0..0
4. Extension.url
Fixed Value	`http://hl7.org/fhir/StructureDefinition/questionnaire-itemControl`
6. Extension.value[x]
Control	1..?
Binding	Unless not suitable, these codes SHALL be taken from QuestionnaireItemUIControlCodes (extensible to `http://hl7.org/fhir/ValueSet/questionnaire-item-control`) User interface controls or widgets used for questionnaire items.
Type	CodeableConcept, date, Meta, Address, Attachment, integer, Count, DataRequirement, Dosage, uuid, Identifier, RatioRange, Coding, SampledData, id, positiveInt, Distance, Availability, integer64, Period, Duration, canonical, Range, RelatedArtifact, base64Binary, UsageContext, Timing, decimal, ExtendedContactDetail, ParameterDefinition, dateTime, code, string, oid, instant, ContactPoint, HumanName, Money, markdown, Ratio, Age, Reference, TriggerDefinition, Quantity, uri, url, Annotation, ContactDetail, boolean, Expression, CodeableReference, Signature, unsignedInt, time
[x] Note	See Choice of Data Types for further information about how to use [x]
Requirements	The data type is CodeableConcept to allow for additional codings that might provide finer-grained control information or specification of specific controls in different rendering environments. CodeableConcept.text is generally unnecessary for this element and should not be sent alone as the use-case for this element is for computable interpretation by rendering engines.

0. Extension
Definition	The type of data entry control or structure that should be used to render the item. Optional Extension Element - found in all resources.
Short	E.g. Fly-over, Table, Checkbox, Combo-box, Lookup, etc.Optional Extensions Element
Comments	Different controls may be appropriate for different item types. It is up to the system rendering a questionnaire as to what controls it will support and for which data types. See additional guidance and examples in the SDC implementation guide.
Control	0..1*
Is Modifier	false
Invariants	ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (extension.exists() != value.exists())
2. Extension.extension
Definition	An Extension May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and managable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
Short	ExtensionAdditional content defined by implementations
Comments	There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

Slicing	This element introduces a set of slices on `Extension.extension`. The slices areUnordered and Open, and can be differentiated using the following discriminators: value @ url
4. Extension.url
Definition	Source of the definition for the extension code - a logical name or a URL.
Short	identifies the meaning of the extension
Comments	The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension.
