gml:NullEnumeration

basicTypes.xsd

 Some common reasons for a null value:   
			
        innapplicable - the object does not have a value
        missing - The correct value is not readily available to the sender of this data.  
                           Furthermore, a correct value may not exist.
        template - the value will be available later
        unknown - The correct value is not known to, and not computable by, the sender of this data. 
                           However, a correct value probably exists.
        withheld - the value is not divulged 
        
        other:reason - as indicated by "reason" string
        
        Specific communities may agree to assign more strict semantics when these terms are used in a particular context.
