Thank you for this, Massimo - this is a nice, compact idiom for using existing validators; I hadn't considered (don't know why not - it's obvious looking at it) this idiom in assigning to a "requires" field. My approach is more general - ANY situation where you want to do some combinatorial logic, or external checking: form.accepts( ..., dbio=False)...
