    Example usage::

         >>> validator = validators.Validator().require_presence_of(

         ...    '127.0.0.1', 'github.com',
         ... )
         >>> validator.validate(uri)
         >>> invalid_uri = rfc3986.uri_reference('imap://mail.google.com')
         >>> validator.validate(invalid_uri)
         Traceback (most recent call last):
