There is a slight difference in syntax between ML-Lex and ML-Yacc. In ML-Lex, semantic actions must be followed by a semicolon but in ML-Yacc semantic actions cannot be followed by a semicolon. The syntax should be the same. ML-Lex also produces structures with two different signatures, but it should produce structures with just one signature. This would simplify some things.
