* @param string $target target frame for form submission. You will rarely use this. Don't use
* it if you don't need to as the target attribute is deprecated in xhtml strict.
* @param mixed $attributes you can pass a string of html attributes here or an array.
* Special attribute 'data-random-ids' will randomise generated elements ids. This
* is necessary when there are several forms on the same page.
* @param bool $editable
* @param array $ajaxformdata Forms submitted via ajax, must pass their data here, instead of relying on _GET and _POST.
