Robert:

There are important environments where the KEK and CEK algorithms are different. Usually, these environment mandate a stronger algorithm for the KEK. This seems like a very reasonable policy, and I think that we should not prohibit it.

Why not just mandate that the CEK and KEK algorithms must be the same? This wouldn't seem to be too much of an imposition. This removes the need for a KDF. If you really want to allow different algorithms, the KDF included seems kind of ad-hoc. I would be more comfortable if a more standard KDF was used. Perhaps the KDF from IEEE P1363 would be appropriate.
