 * Abstract base class for message queues that serialize the AuditRecord into a wire format
 * by using the configured {@link org.openehealth.ipf.commons.audit.marshal.SerializationStrategy SerializationStrategy}
 * and send it to an ATNA repository using the configured {@link org.openehealth.ipf.commons.audit.protocol.AuditTransmissionProtocol},

 * or convert them into FHIR AuditEvents. In this case, implement your own {@link AuditMessageQueue}.
