This EventType inherits all Properties of the AuditEventType. Their semantic is defined in 6.4.3. The SourceNode Property for Events of this type shall be assigned to the NodeId of the Object that the Method resides on. The SourceName for Events of this type shall be "Attribute/Call". Note that one Service call may generate several Events of this type, one per method called. This EventType should be further subtyped to better reflect the functionality of the method and to reflect changes to the address space or updated values triggered by the method.

MethodId identifies the method that was called.

StatusCodeId identifies the StatusCode of the Method executed by the Server.

Note: This Property is optional for backward compatibility and required by Profiles starting with version 1.05.

InputArguments provide the values of the input arguments passed to the Method. This parameter can be null if no input arguments were provided.

OutputArguments provide the values of the output arguments returned by the Method. This parameter can be null if no output arguments were returned.
