yep, totally agree here
that is what I meant when writing to Carsten about this kind of 
validation being dependend on the business object model (this is 
where I use the word 'arbitrary' so often)

woody cannot impose a validation pattern on the business model
and the business model can't impose a validation pattern upon woody
(with validation pattern I mean: methodnames but also 
return-types or exception behavior)

you will need to hook this up yourself, but of course: woody will 
provide the hooks!
