How to validate flash in xhtml?

If you need to validate flash or other embedded stuff in your website!
Firefox does need the embed tag, to display flash. But if you use this tag,
your page will not be valide XHTML !  My way to solve this is the so called
AJAX technology. So the w3c-validator does not find any problems in this
page anymore! See on Zekipopov.

If this has not been wholy helpfully, write an email.
