This Method is used to add a PublishedEventsType Object to the DataSetFolderType Object. The configuration parameters passed in with this Method are further described in the PublishedEventsType defined in 9.1.4.4.1 and the PublishedDataSetType defined in 9.1.4.2.
The settings in the EventNotifier, SelectedFields and Filter are used to configure the data acquisition for the DataSet and are used to initialize the corresponding Properties of the PublishedEventsType.
The DataSetMetaData of the PublishedDataSetType is created from meta-data of the selected Event fields and the settings in FieldNameAliases and FieldFlags.
The Client shall be authorized to modify the configuration for the PubSub functionality when invoking this Method on the Server.
