Recently, the validity of the Ehrenfeucht Conjecture on test sets for morphisms has been established. Based on this result we give an entirely new proof of the decidability of the DOL sequence equivalence problem. The new technique is more powerful and allows us to prove that the sequence equivalence problems for HDOL and DTOL sequences are decidable, as well.We also survey the known results on various generalizations of the DOL sequence equivalence problem.
