	Data object support describes a set of object types that can be used to
	represent the structure of the data source as an object model.  Underlying
	object types are specific to the data source and describe information that
	uniquely identifies instances of the type, properties of the type, and a set
	of services that can perform useful actions given the type.  Mapped object
	types describe a mapping from the underlying object types to generic types
	and properties, and can be consumed by data designers that do not have
	knowledge of any specific data source.
