don't want to add META

[HANAX]

In target mxml document I got META tag but unclosed, seems that after 
transformtion that one was added. Also namespaces was added. In which step this 
is added? Does it have any relation to serializer? I can't still use XMHTL, it 
gives me error, so I added serializer vithout type which I expecct is XML, but 
why META with upeercase and unclosed was added?
Again, my current xmap:
<map:sitemap xmlns:map="http://apache.org/cocoon/sitemap/1.0";>
  <map:pipelines>
    <map:pipeline>
      <!-- Voice -->
      <map:match type="regexp" pattern="^(.*?)([^/]*).mxml$">
        <map:generate src="cocoon://{1}{2}.xml"/>
        <map:transform src="resources/stylesheets/document2mxml.xsl"/>
        <map:serialize/>
      </map:match>
    </map:pipeline>
  </map:pipelines>
</map:sitemap>
