  We give, for general Banach spaces, a characterization of the sequential
lower limit of maximal monotone operators of type (D) and prove its
representability. As a consequence, using a recent extension of the
Moreau-Yosida regularization for type (D) operators, we extend to general
Banach spaces the definitions of the variational sum of monotone operators and
the variational composition of monotone operators with continuous linear
mappings, and we prove that both operators are representable.
