Extension itemControl - Detailed Descriptions

FHIR Infrastructure Work Group Maturity Level: 1InformativeUse Context: Any

Detailed Descriptions for the elements in the extension.

Extension
Element IdExtension
Definition

The type of data entry control or structure that should be used to render the item.

Cardinality0..1
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.

Invariants
Inherited by this element
ele-1RuleAll FHIR elements must have a @value or childrenhasValue() or (children().count() > id.count())
ext-1RuleMust have either extensions or value[x], not bothextension.exists() != value.exists()
Extension.id
Element IdExtension.id
Definition

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

SlicingThis element introduces a set of slices. The slicing rules are:
  • unordered
  • Open
  • discriminators: value:url
Extension.url
Element IdExtension.url
Definition

Source of the definition for the extension code - a logical name or a URL.

Cardinality1..1
Typeuri
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.

Fixed Valuehttp://hl7.org/fhir/StructureDefinition/questionnaire-itemControl
Extension.value[x]
Element IdExtension.value[x]
Definition

Value of extension - must be one of a constrained set of the data types (see Extensibility for a list).

Cardinality1..1
Terminology BindingUser interface controls or widgets used for questionnaire items.
The codes SHALL be taken from Questionnaire Item UI Control Codes; other codes may be used where these codes are not suitable
TypeCodeableConcept
[x] NoteSee 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.
