The non-XML syntax doesn’t allow block elements inside <p>, since they autoclose it. To avoid disrupting the existing layout, insert empty <p></p>s in the same way that the HTML 5 parse error handler would.
<img alt> is required.
<tt>, <div align>, <iframe frameborder> are obsolete.
The one remaining error is on <iframe allowfullscreen>, which I’ve left in to be safe, although it doesn’t seem to have any effect in current browsers.
