Detailed Descriptions for the elements in the extension.

Extension
Element IdExtension
Definition

Provides guidelines for rendering multi-column choices.

Control0..* This element is affected by the following invariants: ele-1
Comments

This can be used for choices drawn from value sets (where additional columns can be drawn from code system properties), for References where columns can be drawn from resource properties and for.

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.

Control0..1
Typestring
Extension.extension
Element IdExtension.extension
Definition

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 manageable, 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.

Alternate Namesextensions, user content
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.

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

The element to display within the column (see notes).

Control1..1
