In XSV, nothing of the sort :-). XSV is designed as a vehicle for exploring W3C XML Schema semantics, and efficiency of any kind is a 2nd-order consideration. Speaking of which, note that if you use any numeric exponents other than min=0/1, you get a _very_ large fsm, and in fact XSV arbitrarily treats any max over 101 as unbounded, and any min over 101 as 101. This isn't even the right optimisation. . . ht -- Henry S.
