A surface patch defines a homogenuous portion of a surface. 
The AbstractSurfacePatch element is the abstract head of the substituition group for all surface patch elements describing a continuous portion of a surface.
All surface patches shall have an attribute interpolation (declared in the types derived from gml:AbstractSurfacePatchType) specifying the interpolation mechanism used for the patch using gml:SurfaceInterpolationType.
