that's what i was talking about, that you didn't discuss the degenerate cases. (in the non-degenerate case x0<x1<...<xn without loss of generality.) in giving a characterization of the c^n functions along the lines i suggested it would probably be more annoying to leave the degenerate cases out than to include them.
