Detailed Descriptions for the elements in the extension.
| Extension | |
| Definition | Information on changes made to the Value Set Definition over time, and also has a contained audit trail of all such changes. |
| Control | 0..* This element is affected by the following invariants: ele-1 |
| Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (xpath: @value|f:*|h:div) ext-1: Must have either extensions or value[x], not both (xpath: exists(f:extension)!=exists(f:*[starts-with(local-name(.), 'value')])) |
| 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. |
| Control | 0..1 |
| Type | string |
| Extension.extension | |
| Definition | May be used to represent additional information that is not part of the basic definition of the element. In order 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 is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. |
| Control | 0..* |
| Type | 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. |
| Slicing | This element introduces a set of slices. The slicing rules are:
|
| Extension.extension(name) | |
| Definition | Label for a set of entries, such as a version. |
| Control | 0..1 |
| Type | Extension |
| Comments | Typically, a value set will have a set of history entries for each major publication milestone. |
