* @param SimpleXMLElement $element The SimpleXMLElement object representing the `<field>` tag for the form field object.
* @param mixed $value The form field value to validate.
* @param string $group The field name group control value. This acts as an array container for the field.
* For example if the field has name="foo" and the group value is set to "bar" then the
* full field name would end up being "bar[foo]".
* @param Registry $input An optional Registry object with the entire data set to validate against the entire form.
