Comment:

 The issue at heart here, Is that your doctype does not allow the usage of
 {{{<embed>}}} which is required for older non-XHTML compliant browsers.

 In an environment where you're using XHTML, you'll probably need to filter
 out the non-compliant elements, as oEmbed is designed to use the trusted
 code from the embedder. And its unlikely WordPress is going to mess with
 the results, because removing {{{embed}}} means removing support for older
 browsers (No idea which browsers..)

 In your case, something like this (untested) will achieve it:
 {{{
 add_filter('oembed_dataparse', '_strip_embed');
 function _strip_embed($data) {
     $data = preg_replace('|<embed.+?>.*?</embed>|i', '', $data);
     return $data;
 }
 }}}
