When FlattenStructure is enabled, ParseFirstElementOnly will always be regarded as true. Therefore a column would not be added to the data structure if it was empty in the first row of a table (first childnode of the corresponding XML element). If this option is set to true, empty XML nodes will be registered as columns even when FlattenStructure is enabled.
