Extension inheritedExtensibleValueSet - Detailed Descriptions

FHIR Infrastructure Work Group Maturity Level: 1 Informative Use Context: Any

Detailed Descriptions for the elements in the extension.

Extension

Element Id Extension

Definition

A reference to an extensible value set specified in a parent profie in order to allow a conformance checking tool to validate that a code not in the extensible value set of the profile is not violating rules defined by parent profile bindings.

Cardinality 0..* This element is affected by the following invariants: ele-1

Comments

This extension is only needed where the binding strength is 'extensible', the parents are also 'extensible'. This allows a validator to work around the fact that restricting extensible value sets in child profiles loses constraints out of the parent profiles, (e.g. codes to be used when appropriate).

Invariants

Inherited by this element

ele-1 Rule All FHIR elements must have a @value or children unless an empty Parameters resource hasValue() or (children().count() > id.count()) or $this is Parameters

ext-1 Rule Must have either extensions or value[x], not both extension.exists() != value.exists()

Extension.id

Element Id Extension.id

Definition

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

Cardinality 0..1

Type id

Extension.extension

Element Id Extension.extension

Definition

An Extension

Cardinality 0..0

Type Extension

Invariants

Inherited by this element

ele-1 Rule All FHIR elements must have a @value or children hasValue() or (children().count() > id.count())

ext-1 Rule Must have either extensions or value[x], not both extension.exists() != value.exists()

Slicing This element introduces a set of slices. The slicing rules are:

unordered
Open
discriminators: value:url

Extension.url

Element Id Extension.url

Definition

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

Cardinality 1..1

Type uri

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 Value http://hl7.org/fhir/StructureDefinition/elementdefinition-inheritedExtensibleValueSet

Extension.value[x]

Element Id Extension.value[x]

Definition

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

Cardinality 1..1

Type Choice of: uri, canonical(ValueSet)

[x] Note See Choice of Data Types for further information about how to use [x]
