 * attributes and so forth. There are a few cases where these old items might be needed for example in email applications or with Flash
 *
 * However you should NOT use this plugin if you are building some system that produces web contents such as a CMS. All these elements are
 * not apart of the newer specifications for HTML and XHTML.
