That's not quite right. The terms top-down development and
stepwise refinement are both current, stepwise refinement
is a particular approach that is in the general top down
category, i.e. a stepwise refinement approach is an example
of top down approaches, but not all top down approaches would
be considered to be stepwise refinement.
