 This option defines the pattern used to validate the email address. Valid values are:
 
-* ``loose`` uses a simple regular expression (just checks that at least one ``@``
-  character is present, etc.). This validation is too simple and it's recommended
-  to use one of the other modes instead;
 * ``html5`` uses the regular expression of the `HTML5 email input element`_,
   except it enforces a tld to be present.
 * ``html5-allow-no-tld`` uses exactly the same regular expression as the `HTML5 email input element`_,
