The cardinality or value of this element may be affected by these constraints: ele-1

Constraints
  • 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()

Short description

Additional content defined by implementations

Alternate names

extensions, user content

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.

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.

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.
