  WTForms uses lists of validators. That approach helps to separate validators

  Validators are simple objects. ``__init__`` method provides a way to configure validator.
  ``__call__`` method provides a way to process validation.
  
  Validation is bound to forms objects. This has been made to provide ``EqualTo``
  functionality. Reflects connections between form fields.
  
  WTForms users ``ValidationError`` and ``StopValidation`` exceptions.
  ``ValidationError`` is used for errors forwarding.
  ``StopValidation`` is used to skip steps. Thus some validation steps could be optional.
