This is useful, for example, in defining boundaries -- it could be a Data2D< NULL_DataType, Location, NULL_DataType >. The first NULL_DataType states that it is merely a container of Data1D< Location, NULL_DataType > (each of which is a continous set of line segments). The second NULL_DataType states that it has no data value associated with it.
