ok, so instead of modifying the mesh.xml format, one would just read in another function.xml that would later be used in computing the element tensor? So, in this sense, the higher order coordinate information for each triangle would be viewed as some extra coefficients that Tabulate_Tensor would use in computing the local FE matrix. This way, the only thing to modify would be FFC (and UFC maybe). In other words, when you assemble the form, you MUST pass this additional function to assemble?
This sounds good, but I am not completely sure. - Shawn
