Hi,
yesterday a colleague approached me asking why OSM data
doesn't comply to the Simple Feature specification[1]
I guess the honest answer is very likely that most people invovled in
designing anything at OSM have no prior GIS experience. Most of us are
amateurs. We design stuff that we think

The wiki page you cited says In general, a 2D geometry is simple if
it contains no self-intersection. - what do they mean by 2D
geometry? Specifically, would a self-intersecting *line* be allowed?
