When tagging a village/town/city, I can use `place=city/town/suburb...` to mark it as a town etc. I'm not quite clear on how to use this tag: - If I understand correctly, the Wiki recommends: 1) putting the `place=` tag on a node in the center, and 2) drawing the official boundary of the place as a way and tagging it with `administrative=boundary` (http://wiki.openstreetmap.org/wiki/Key:place , section "Core values / As areas" ). - However, in the database I sometimes see places which have both an area tagged `place=` *and* a (different) area tagged `boundary=administrative`. One example would be Dieren (NL) (search for "Dieren" on Nominatim). What is the point of this? Isn't this contradictory? Or are there situations where the area of the place differs from its official boundary? So should I use `place=` on a node or on an area? If the latter, when would the area of a `place=*`, be different from its official boundary?boundary? *This question was prompted by the discussion on my answer to [Way in wrong country][1].* [1]: http://help.openstreetmap.org/questions/3892/way-in-wrong-country
