Also note that '1' and '0' are accepted values for this type. Kasimier certainly has a more precise idea about this. I'm surprized this kind of problem isn't caught by the huge OASIS datatype regression tests.
Thanks for that Daniel. Yes, just confirmed that the values 0 and 1 validate OK while any other numeric value like (2,3,-0,-1 etc) fail as expected, so no issues there.
Will wait for comments from Kasimier.
Bas.
