/// The FdoIGeometricAggregateAbstract class is an aggregate Geometry (abstract) type.
/// FdoIGeometricAggregateAbstract is a single Geometry that is a collection of other geometries.
/// There is no requirement that the geometries interact spatially.
/// Non-abstract derived types should have at least one accessor that returns objects of the appropriate contained type.
