My XML is getting messed up using the FB markup language.  For Example:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp "&#x00A0;"> ]>
<xsl:stylesheet 
    version="1.0" 
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
   xmlns:msxml="urn:schemas-microsoft-com:xslt"
 xmlns:fb="http://www.facebook.com/2008/fbml"
 xmlns:umbraco.library="urn:umbraco.library" xmlns:Exslt.ExsltCommon="urn:Exslt.ExsltCommon" xmlns:Exslt.ExsltDatesAndTimes="urn:Exslt.ExsltDatesAndTimes" xmlns:Exslt.ExsltMath="urn:Exslt.ExsltMath" xmlns:Exslt.ExsltRegularExpressions="urn:Exslt.ExsltRegularExpressions" xmlns:Exslt.ExsltStrings="urn:Exslt.ExsltStrings" xmlns:Exslt.ExsltSets="urn:Exslt.ExsltSets" xmlns:MailEngine="urn:MailEngine" 
  exclude-result-prefixes="fb msxml umbraco.library Exslt.ExsltCommon Exslt.ExsltDatesAndTimes Exslt.ExsltMath Exslt.ExsltRegularExpressions Exslt.ExsltStrings Exslt.ExsltSets MailEngine ">

<xsl:output method="xml" omit-xml-declaration="yes"/>
<xsl:param name="currentPage"/>
<xsl:variable name="domain" select="'http://'" />
<xsl:variable name="url" select="concat($domain,umbraco.library:RequestServerVariables('SERVER_NAME'))" />
<xsl:variable name="AppId" select="/macro/AppId" />
<xsl:template match="/">
<div id="fb-root"></div>
<script src="http://connect.facebook.net/en_US/all.js#appId={$AppId}&amp;xfbml=1" type="text/javascript"></script>
<fb:comments xid="{$url}{umbraco.library:NiceUrl($currentPage/@id)}" numposts="10" width="225" publish_feed="true"></fb:comments>

</xsl:template>
</xsl:stylesheet>

My output is:

   <div id="fb-root"></div>
   <script src="http://connect.facebook.net/en_US/all.js#appId=000&amp;xfbml=1" type="text/javascript"></script>
   <fb:comments xid="http://www.mysite.com/default.aspx" numposts="10" width="225" publish_feed="true" xmlns:fb="http://www.facebook.com/2008/fbml" /> 

My problem is at the end of the fb element, I can't get rid of it!
