Using respect validation?

[royopa]

What do you think about use the Respect Validation Library as a requirement for this project?
Example:
Maybe use the Respect Validation as a requirement in composer and return a exception when
v::cpf()->validate('02650306461'); return false.

I thinking about it and Respect\Validation component is awesome.

So, I have doubts about responsibility in this case, I don't know if documents validation must be done from Respect\Validation or maybe this document component integrates with Respect\Validation.

Maybe move Modulo11 to Respect\Validation, because this class has a configurable rule to validate numbers.
