The contents of the XML file produced when exporting a realm does not indicate which categories are hidden.
This means that if the XML file is used to create a new realm, then the "hidden" categories are visible in the new realm.
It also means that my CSV2RW tool can't hide the "hidden" categories when presenting a list of categories to be used for the import creation.
