<documentation>A gml:CompositeSurface is represented by a set of orientable surfaces. It is geometry type with all the geometric properties of a (primitive) surface. Essentially, a composite surface is a collection of surfaces that join in pairs on common boundary curves and which, when considered as a whole, form a single surface.
surfaceMember references or contains inline one surface in the composite surface.
The surfaces are contiguous.</documentation>
