Henrique Moody	d53811f7b7	Remove user-defined optional values ... Since we have NotOptional rule now, we must keep the same opposite behaviour between these two rules. This commit also improve and increase tests from Optional rule and updates the documentation. No tests was made for messages on MODE_DEFAULT because it's not possible for a while since we don't have such much granularity control, but after some fixes on Not rule, maybe we will be able to do that, that's why I kept the messages on OptionalException.	2015-10-15 11:14:20 -03:00
