Returns the HTML to render this form (or content) element to the screen. $name is the HTML machine name. $element is an array containing all we need to render it. If you want default values to be taken from the SESSION (because we had form_errors, say, and we want values to keep what we had between submissions) specify the callback to use in the use_session_submission_values_for_callback variable.
