http://hl7.org/fhir/StructureDefinition/diagnosticReport-replaces|4.0.1

The report replaces the target resource. For example, when a final anatomic pathology report replaces a preliminary anatomic pathology report replaces where the subsequent observation of case and report may be on more or different material (specimen). Note that this is not same concept as` DiagnosticReport.status` = preliminary of final, but industry definition of preliminary and final.
