A MultiCurve is simple if and only if all of its elements are simple and the only intersections between any two elements occur at Points that are on the boundaries of both elements.
This means that MultiLineString containing two elements with coincident line segments is not simple, since the elements intersect in their interior points.
MULTILINESTRING ((0 0, 100 100), (100 100, 0 0))
This is reported incorrectly as simple by Geometry.isSimple() and IsSimpleOp.
