/**
 * Because some editors add a lot of new elements with the id attribute set,
 * Wysiwyg provides a way to exclude such ids from the ajax_html_ids[] parameter
 * sent in AJAX requests. Serverside POST limits such as PHP's max_input_vars
 * could otherwise cause the request to be rejected.
 *
 * The filter gathers a list of jQuery selectors from a global list in
 * Drupal.wysiwyg.excludeIdSelectors, joins them with a comma separator and
 * wraps them in "[id]:not[...]", which is then run on the document the same way
 * Drupal core gathers the ids on every AJAX request.
 *
 * To add to the filter, set a unique key to Drupal.wysiwyg.excludeIdSelectors
 * and set its value to an Array holding one or more selector strings which
 * would match the element(s) to exclude.
 *
 * Beware not to match elements which are not removed before the actual request
 * is performed, or Drupal may accidentally reuse the same id for new elements.
 *
 * Below is a sample from ckeditor.inc matching every id starting with 'cke_'.
