Its definition is derived from the standard FHIR SearchParameter and it uses the [Conformance expectation extension](http://hl7.org/fhir/StructureDefinition/capabilitystatement-expectation) to define additional expectations for the following SearchParameter elements:\n- `multipleAnd`\n- `multipleOr`\n- `comparator`\n- `modifier`\n- `chain`\n\nIt **SHALL NOT** be used as a search parameter for search. Servers and Clients **SHOULD** use the standard FHIR SearchParameter.\n",
