Thanks for your reply, sthenbelle. The category was Regional: Europe: Austria: Travel and Tourism which includes 48 sites listed under that heading.
However the Austria section seems to be a bit mixed-up, with, for example, Graz Airport listed under the section above but Salzburg and Vienna Airports under Regional: Europe: Austria: Business and Economy: Transportation. Likewise some towns or villages are listed under the category above and some under Regional: Europe: Austria: Localities. Thus my question about a possible pending reorganisation....
