A function is semismooth if and only if its subdifferential is semicontinuous. All the semicontinuous operators form a big linear subspace of the maximal normal operator space. By "big," we mean that this subspace includes all the continuous operators and all the maximal monotone operators. All the decomposable maximal normal operators form another big subspace.
