* All we need for this is our `EventType`. Once we have our event node, which is saved internally as an `ObjectNode`,
* we can define the attributes the event has the same way we would define the attributes of an object node. It is not
* necessary to define the attributes `EventId`, `ReceiveTime`, `SourceNode` or `EventType` since these are set
* automatically by the server. In this example, we will be setting the fields 'Message' and 'Severity' in addition
* to `Time` which is needed to make the example UaExpert compliant.
