 In MapGuide, the null CS (Coordinate System) means the CS is XY-M (with
 X-axis, Y-axis, the unit is meter).
 However in Fusion code, the null CS (Coordinate System) means the CS is
 "EPSG:4326" (the unit is degree).
 So if there is only a null CS MapGuide layer in the map, you'll find the
 projection for the layer is "EPSG:4326", not the correct "XY-M".
 So we need to change the WKT for null CS to be
    LOCAL_CS["Non-Earth (Meter)",LOCAL_DATUM["Local Datum",0],UNIT["Meter",
 1],AXIS["X",EAST],AXIS["Y",NORTH]]"
 to make it "XY-M"
