There is no semantic difference in creating group/cluster/site relation and tagging with name and creating multipolygon and tagging it with name. If you want to distinguish "group of islands" from "group of lakes" in both cases you need additional tag or special processing. > But still, it only works for areas, you cannot use multipolygons for groups > of nodes or groups of lines, or mixes of these. > Yeah, multipolygons are superior for for cases like mentioned - set of areas. If you want group of nodes/ways then sadly it stops being a great solution.
