> -If some domain value is compared to Null value, the current implementation
> will cause either InvalidOperationException or FALSE. Such cases should
> result in NULL.-
> Many primitive operators including arithmetic and comparison do not consider
> three valued logic. This patch corrects this problem. The original issue
> title was 'Comparison of primitive values including null value should return
> NULL.' This issue was expanded for null value handling of all primitive
> operators.
