Abstract.   Recently L.R. Rubin and P.J. Schapiro have considered inverse sequences X of metrizable spaces Xi, whose extension dimension dim Xi P, i.e., P AE(Xi), where P is an arbitrary polyhedron (or CW-complex). They proved that dim XP, where X = lim X. The present paper generalizes their result to inverse sequences of stratifiable spaces, giving at the same time a more conceptual proof.
