Recently there has been some interest in rule formaltsms for describing morphologically significant regularities in orthography of words, largely influenced by the work of Koskenniemi. Varioue implementationa of these rules are possible, but there are some weaknesses in the formalism as it stands. An alternative specification formalism is possible which solves some of the problems. This new formalism can be viewed as a variant of the "pure'" Koskenniemi model with certain conetraints relaxed.
