class MyRule implements Validation\Rule\Rule
{
    public function getMessage()
    {
        return 'myRuleName';
    }

    public function pass($v, Validation\Validator $context)
    {
        return $v == 'ok';
    }

    public function getMessage()
    {
        return '%s is not equal to "ok"';
    }
}
