  A set of consistency conditions is derived for the massless sector of the
D-dimensional E(8)xE(8) heterotic string. Under the solvable Lie algebra gauge
these conditions are further formulated explicitly in terms of the dilatons and
the axions. It is then shown that these consistency conditions which are
satisfied by the solution space give way to an implicit decoupling between the
coset scalar sector namely the dilatons and the axions and the gauge fields of
the theory.
