No, it's different:

        class constrained
        {
                struct helper : compressed_pair<empty1, empty2>
                {
                        T value;
                }

                helper member;
        }

The interfaces are described here http://tinyurl.com/5wnfpj in the Parameters
section. Morover, there may be additional requirements imposed by particular
functions (e.g., swap requires that the policies are swappable) -- they are
mentioned in the documentation of those functions.
