Are these the elements that have values and gradients as degrees of freedom in each vertex? Baerbel Janssen has implemented the Adini element that does something similar I believe. Do you plan on using this for a mesh with only rectangular cells, or does it have general, unstructured meshes? The difficulty with all of these elements that have derivatives as degrees of freedom is the transformation from reference to real cell since the xi_1 derivative may be the x_1 derivative on one cell that is a rectangle parallel to the coordinate axes, but may be the derivative in an entirely different direction if the neighboring cell is not a rectangle.
