I had the same question (posted here some weeks ago). Didn't get any answer,
but IMHO xfbml namespace is not considered a "standard" namespace for html
documents so it's not recognized by the validator.

A simpliest workaround to get your pages validate is to use something like:

<script type="text/javascript">/* <![CDATA[ */

document.write('<fb:like></fb:like>');

/* ]]> */</script>

This is considering your document is XHTML (to use CDATA)
