Dear woodpeck! I add name tags to borders for faster border identification for working purposes. Later, this tagging will be removed (as is the case in https://www.openstreetmap.org/relation/17266239). The source of the data is the official data contained on the websites of the Diocesan Curias and data from the Secretariat of the Polish Episcopal Conference obtained for the purpose of creating maps on OSM, so they are compliant with the OSM license.
