Operation Not Supported

Extension used in a CapabilityStatement to indicate that the parent resource type or search parameter is not supported for use in a bulk data export operation. For example, the following extension would indicate that the `AllergyIntolerance.clinical-status` search parameter may not be used in a `_typeFilter` parameter on this server. ``` "searchParam": [{ "name": "clinical-status", "type": "token", "extension": [{ "url": "http://hl7.org/fhir/uv/bulkdata/Extension/operation-not-supported", "valueCanonical": "http://hl7.org/fhir/uv/bulkdata/CapabilityStatement/bulk-data" }] }] ```
