This Method is used to create a PublishedDataSets Object of type PublishedDataItemsType and to add it to the DataSetFolderType Object. The configuration parameters provided with this Method are further described in the PublishedDataItemsType defined in 9.1.4.3.1 and the PublishedDataSetType defined in 9.1.4.2.
The settings in the VariablesToAdd are used to configure the data acquisition for the DataSet and are used to initialize the PublishedData Property of the PublishedDataItemsType.
The DataSetMetaData of the PublishedDataSetType is created from meta-data of the Variables referenced in VariablesToAdd 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.
