according to the wiki "municipalities with facilities should have the official translated names under name:nl=*, name:fr=* and name:de=* (depending on which language facilities are offered), the name=* tag should contain only the official name in the primary language"
so from what I interpret the tag name=* in 'Kelmis 7 La Calamine' should be only in German like it used to be before. @Jay May can you revert/undo your name changes?
