Detailed Descriptions for the elements in the extension.

Extension

Element Id

Extension

Definition

Information on changes made to the Value Set Definition over time, and also has a contained audit trail of all such changes.

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

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.

0..1

Extension.extension

Element Id

Extension.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 Names

extensions, 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.
