anchor.diff:  For dealing with implicitly defined Coordinate Systems, you can use the
   *_CoordinateAxes* attribute:
   
  -[code,bash]
  +[source,bash]
   ----
    int Lambert_Conformal;
      Lambert_Conformal:grid_mapping_name = "lambert_conformal_conic";
  
positive.code: You can use any Variable as the Coordinate Transform Variable; here’s an
  example using the vertical Coordinate Axis to hold a vertical transform:
  
  [code,bash]
  ----
  dimensions:
     y = 428;
  
negative.code: will apply to any CoordinateSystem that has both *GeoX* and *GeoY*
  Coordinate axes.
  
  [source,bash]
  ----
     char VerticalCoordinateSystem;
       VerticalCoordinateSystem:_CoordinateTransformType = "Vertical";
