Hi Ed,
You misunderstood my point, "return OK" in my mind is "no exception is
throwing".
You know all my marshall is not OK because of this validation. All the
field with "?", I have to generate an dummy field in order to pass
validation, this against the DTD definition of an option field. That is why
I think this is a bug.
Thank you
Yuemin

Hi Yuemin,
Is your point that v.validate(_PAYINFO) should simply return "false" if
it encounters a problem, instead of throwing an exception?
