[Validator] CascadedValidator

I have just uploaded the CascadedValidator.

The extension is a simple Validator. It can be used to validate a model attribute with any other built in or custom validator. It is only evaluated if another attribute fulfills certain preconditions (checked via any built in or custom validator).

Bug reports and feedback are welcome.

Hello, I followed suit and did not understand. VocĂȘ pode me ajudar com os detalhes do uso?
