and propagate to column definition

Here's what I am using to accomplish this in the seampay example.

I don't understand how PropertyConstraint works, so I was unable to implement apply(). I'll be happy to do that part too, if someone can explain exactly what it does. (the docs are lacking in that regard)

you should do something similar to what LengthValidator is doing but with setPrecision and setScale

Still need translation

numeric value out of bounds (<{integerDigits} digits>.<{fractionalDigits} digits> expected)

brazilian portuguese (pt-br)
valor numérico fora do padrão (esperado <{integerDigits}> dígitos,<{fractionalDigits} dígitos)

Danish/DK:
værdien er ikke inden for det forventede (<{integerDigits} heltal>.<{fractionalDigits} decimaler>)

it-IT: "valore numerico fuori dai limiti (atteso <{integerDigits} cifre>.<{fractionalDigits} cifre>)"
