gml:MultiPointCoverage

In a gml:MultiPointCoverage the domain set is a gml:MultiPoint, that is a collection of arbitrarily distributed geometric points.
The content model is identical with gml:DiscreteCoverageType, but that gml:domainSet shall have values gml:MultiPoint.
In a gml:MultiPointCoverage the mapping from the domain to the range is straightforward.
-	For gml:DataBlock encodings the points of the gml:MultiPoint are mapped in document order to the tuples of the data block.
-	For gml:CompositeValue encodings the points of the gml:MultiPoint are mapped to the members of the composite value in document order.
-	For gml:File encodings the points of the gml:MultiPoint are mapped to the records of the file in sequential order.

gml:id [1..1]xsd:IDThe attribute gml:id supports provision of a handle for the XML element representing a GML Object. Its use is mandatory for all GML objects. It is of XML type ID, so is constrained to be unique in the XML document within which it occurs.from type gml:AbstractGMLType
