| Title | SDC Template Extract Extension (carrier) |
| Realm | ch |
| Authority | hl7 |
| Description | Carrier/placeholder extension used only inside an SDC template-based $extract template to build a whole FHIR Extension via %factory.Extension at a location a value directive cannot reach (e.g. a primitive element's _element.extension). Its %factory.Extension result replaces this carrier during extraction, so it never appears in extracted output. |
