12377	validator does not detect intersecting rings in multipolygon	cmuelle8	team	"Find test case attached.  Additionally, touching inner rings should be warned about, as this will lead to ""boundary"" segments of the area not bounding the area, i.e. segments that have ""outside"" on both sides and hence are not boundaries. This contradicts every reasonable understanding of what an area is.

The least common denominator is, that an area has an exact outline enclosing it (it does not matter if there are more than one patches, or even holes, for this).  By declaring touching inner rings to be a valid part of multipolygons, we define outline parts that cannot be an outline to be a valid outline - which is, erm, complete nonsense.
