### Messages

Error | StructureDefinition.version | Values for version differ: '2.1.0' vs '2.2.1'
Information | StructureDefinition.date | Values for date differ: '2024-12-11T18:49:53+00:00' vs '2026-03-26T15:54:25+00:00'
Information | CommunicationRequest.language | Example/preferred bindings differ at CommunicationRequest.language using binding from CRDCommunicationRequest
Information | StructureDefinition.comment | Values for comment differ: 'This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again. Contained resources may have profiles and tags In their meta elements, but SHALL NOT have security labels.' vs 'Any references found in this resource, with the exception of 'Patient' could potentially be resource-specific and thus transmitted as contained resources.'
Warning | CommunicationRequest.contained | Elements differ in definition for mustSupport: 'false' vs 'true'
Error | CommunicationRequest.replaces | Type Mismatch: Reference([CanonicalType[http://hl7.org/fhir/us/davinci-crd/StructureDefinition/profile-communicationrequest]]) vs Reference([CanonicalType[http://hl7.org/fhir/us/davinci-crd/StructureDefinition/profile-communicationrequest]])
Information | StructureDefinition.comment | Values for comment differ: 'potentially relevant for CRD in some situations.' vs 'Observations **SHOULD** use US Core profiles when applicable, but not all relevant observations have appropriate US Core profiles (and there are too many to practically list all US Core profiles).'
