description: An extension that mimics the default FHIR `Resource.category` element that can be used if multiple categories need to be captured, while the cardinality of the core element is 0..1. Resource types where this is the case are for example MedicationAdministration, MedicationDispense, MedicationStatement and Procedure. Note that in the current FHIR R5 build of these resource types, the cardinality of `.category` has been changed to 0..*.
