Yeah, like I said, it's not an optimal solution.

I'm not sure how to handle the case you describe (where one control has 
different constraints based on which form is being submitted). None of the 
ideas I've had or seen are really simple. (It's worth noting that XForms 
doesn't handle this case either, in fact!)

The current solution is to fixup things via the onsubmit attribute (since 
it fires just before validation). But that does rather suck.
