The PublishedEventsType ObjectType is a concrete type and can be used directly.
The EventNotifier is defined in 6.2.2.7.1.
The SelectedFields is defined in 6.2.2.7.2.
The index into the list of entries in the SelectedFields has an important role for Subscribers. It is used as handle to reference the Event field in DataSetMessages received by Subscribers. The index may change after configuration changes. Changes are indicated by the ConfigurationVersion and applications working with the index shall always check the ConfigurationVersion before using the index. If a change of the SelectedFields adds additional fields, the MinorVersion of the ConfigurationVersion shall be updated. If a change of the SelectedFields removes fields, the MajorVersion of the ConfigurationVersion shall be updated. The Property ConfigurationVersion is defined in the base ObjectType PublishedDataSetType.
The Filter is defined in 6.2.2.7.3. A change of the Filter does not affect the ConfigurationVersion since the content of the DataSet does not change.
