The powers of 2 in the triangle inequalities on p.\ 1427 should not be there.
Condition 2 should also include the requirement that
\nabla^{10}\phi be continuous in \emph{both} arguments, i.e. in R_S \times R^p
There should not be any 1/2 in the definition of J on p.\ 1426.
The plus before the final quadratic form in (38) should be a minus.
The second $\theta_k$ in the proof of Lemma 6 needs a $^{\infty}$.
The final argument in the proof of Lemma 6 applies only to surrogate
functions that are separable in their first argument. :-(
