gml:MultiSurfaceCoverage

In a gml:MultiSurfaceCoverage the domain is partioned into a collection of surfaces comprising a gml:MultiSurface.  The coverage function than maps each surface in the collection to a value in the range set.
The content model is identical with gml:DiscreteCoverageType, but that gml:domainSet shall have values gml:MultiSurface.
In a gml:MultiSurfaceCoverage the mapping from the domain to the range is straightforward.
-	For gml:DataBlock encodings the surfaces of the gml:MultiSurface are mapped in document order to the tuples of the data block.
-	For gml:CompositeValue encodings the surfaces of the gml:MultiSurface are mapped to the members of the composite value in document order.
-	For gml:File encodings the surfaces of the gml:MultiSurface are mapped to the records of the file in sequential order.
