[Imports] Import field areas in Viersen, Germany with place=locality

The outlines come from the cadastral (property) map. There are 1 to 5 separate outlines per place, some are also really small.
That would be too much detail, we don´t want to copy the property map to osm so we would need to simplify the outlines by hand.
(If you follow that idea to the end we have to copy all parcels from the property map and map addresses not to buildings but to that fields.)
Since these places, we are talking about, are rather small, a single point can give you a good idea there this place is. 
Like " ´Three Oaks´ is near a particular crossing in the woods ..." No one normally knows the exact fields that have that name.
With a point it would be the same way like these names are presented in walking maps. 
On the other hand you have no idea how wide this place spreads.
But regarding the fact that these places are meant for orientaion this should work, like in our example linked in the first posting:
http://www.openstreetmap.org/?lat=51.25254&lon=6.36924&zoom=16&layers=M
If we introduce a (new) special tag it will take a long time until these information will find its way on walking maps if it happends at all. (But thats not our main concern)

It might be an option to use a (new) specific place value for Gewann and add this to existing features (or maybe create multipolygons). IMHO these would better be tagged on areas than on nodes, as nodes, especially locality nodes convey really few info about the extension of the area where they belong to, while they do have very distinct borders in the real world
