Both default to TRUE. If set to false, you need to explicitly specify "length" and/or "type" in the parameter of hasColumn that specifies the validators for that column.
- validators codes are now string instead of integers (constants)
- validating is now handled in record level
- added new component Doctrine_Validator_ErrorStack
- new methods Doctrine_Record::isValid() and Doctrine_Record::getErrorStack()
- errorStack now as a record instance variable
