Reasons for void values.
-- Description --
NOTE 1 INSPIRE application schemas may propose extensions to this code list, if required.
NOTE 2 It is expected that additional reasons will be identified in the future, in particular to support reasons / special values in coverage ranges.

                    | Unknown |  |  | The correct value for the specific spatial object is not known to, and not computable by, the data provider. However, a correct value may exist. 
-- Description --
EXAMPLE When the "elevation of the water body above the sea level" of a certain lake has not been measured, then the reason for a void value of this property would be 'Unknown'.
NOTE 'Unknown' is applied on an object-by-object basis in a spatial data set. | 
                
                    | Unpopulated |  |  | The characteristic is not part of the dataset maintained by the data provider. However, the characteristic may exist in the real world.
-- Description --
EXAMPLE When the “elevation of the water body above the sea level” has not been included in a dataset containing lake spatial objects, then the reason for a void value of this property would be ‘Unpopulated’.
NOTE The characteristic receives this value for all objects in the spatial data set. | 
                
                    | Withheld |  |  | The characteristic may exist, but is confidential and not divulged by the data provider. |
