Since there still seems to be debate about some cases, would anyone object to type=multipolygons and those missing type=* tags that are over a week and others over a year?
Then we can debate the validity of a relation not referenced by anything in the database and not referencing anything itself. > From: Paul Norman [mailto:penor...@mac.com] > Subject: [OSM-talk] Proposed mechanical edit: Empty Relations > > Through editor errors or other mistakes there are a number of relations > in OSM which have no members.
