FaceGrids vs GridLines

How come I can do: Plot[Sin[x], {x, 0, 2Pi}, GridLines -> { {Pi}, None }] while when I try: Plot3D[Sin[x]Cos[y], {x, 0, 2Pi}, {y, 0, 2Pi}, FaceGrids -> { { {0, 0, 1}, { {Pi}, None } } } ] I get an error message: FaceGrids::fgstl: None is not a valid grid style specification. although Wolfram on page 790 says: " ... These specifications have the form described in the notes for GridLines." And more important: How can I get FaceGrids in one direction and not in another (stupid tricks like "FaceGrids -> { { {0, 0, 1}, { {Pi}, {box} } } }" where box coincides with one of the box-edges - excluded), without the annoying error message "FaceGrids::fgstl"(stupid tricks like "Off[FaceGrids::fgstl]" - excluded) ?
