AFAIU, the is_in tag is used for search index. My OSM dump (part of Russia) has several regions, where is_in tag is put on many streets.
You are supposed to be able to draw a polygon, marked with "place=village/town/suburb(etc)" and "place_name=whatever" and then all streets inside the polygon would behave as if they included an "is_in=whatever" tag on the way. POIs would behave similarly. See http://wiki.openstreetmap.org/wiki/FAQ#What_makes_a_road_belong_to_a_city.3F The "is_in" tag is supposed to be used only in exceptional cases. I've been doing this around my area (South Wales) and where possible, flagging the polygon with "landuse=residential(etc)" which shades the map nicely: See http://www.openstreetmap.org/?lat=51.53023&lon=-3.67813&zoom=15&layers=0B00F... I sure hope mkgmap makes use of these polygons or I'm wasting my time!! Steve
