/**
 * A {@linkplain Complex complex} with all the geometric properties of a surface. Thus, this
 * composite can be considered as a type of {@linkplain OrientableSurface orientable surface}.
 * Essentially, a composite surface is a collection of oriented surfaces that join in pairs on
 * common boundary curves and which, when considered as a whole, form a single surface.

 * @revisit This interface extends (indirectly) both {@link org.opengis.spatialschema.geometry.primitive.Primitive} and
 *          {@link org.opengis.spatialschema.geometry.complex.Complex}. Concequently, there is a clash in the semantics
 *          of some set theoretic operation. Specifically, <code>Primitive.contains(...)</code>
 *          (returns FALSE for end points) is different from <code>Complex.contains(...)</code>
 *          (returns TRUE for end points).
