Extension: Messages

Official URL: http://hl7.org/fhir/StructureDefinition/cqf-messages				Version: 1.0.0-ballot
Standards status: Trial-use			Maturity Level: 3	Computable Name: Messages

An OperationOutcome that contains any information, warning, and/or error messages that were generated while processing an operation such as $evaluate or $prepopulate.

Operation processing often generates information, warning, or error messages that don’t necessarily stop processing (so would not result in an OperationOutcome as the overall result of the operation) but still need to be communicated as part of the result. This extension allows for these messages to be included as a reference to an OperationOutcome resource (typically included as a contained resource in the result of the operation).
