An IMultiCurve is a 1-dimensional IGeometryCollection whose elements are ICurves.
IMultiCurve is a non-instantiable class in this standard; it defines a set of methods for its subclasses and is included for reasons of extensibility.
An IMultiCurve 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.
The boundary of a IMultiCurve is obtained by applying the "mod 2" union rule: A Point is in the boundary of a IMultiCurve if it is in the boundaries of an odd number of elements of the IMultiCurve
A MultiCurve is closed if all of its elements are closed. The boundary of a closed MultiCurve is always empty.
A MultiCurve is defined as topologically closed.
