This EventType inherits all Properties of the AuditSessionEventType. Their semantic is defined in 6.4.7. The SourceName for Events of this type shall be "Session/CreateSession". The ClientUserId is not available for this call thus this parameter shall be set to the "System/CreateSession".

The additional Properties defined for this EventType reflect parameters of the Service call that triggers the Event.

SecureChannelId shall uniquely identify the SecureChannel. The application shall use the same identifier in all AuditEvents related to the Session Service Set (AuditCreateSessionEventType, AuditActivateSessionEventType and their subtypes) and the SecureChannel Service Set (AuditChannelEventType and its subtypes).

ClientCertificate is the clientCertificate parameter of the CreateSession Service call.

ClientCertificateThumbprint is a thumbprint of the ClientCertificate. See OPC 10000-6 for details on thumbprints.

RevisedSessionTimeout is the returned revisedSessionTimeout parameter of the CreateSession Service call.
