namespace in html tags

["Stephen Tredrea" <stephen.tredrea@xxxxxxxxxxxxx>]

Is there any way to stop a transformation putting the namespace declarations
into html tags?

For example, this XSL...

<xsl:stylesheet version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
  xmlns:dc="http://purl.org/dc/elements/1.1/";
  >
<xsl:output method="xml" omit-xml-declaration="yes"/>

<xsl:template match="/">
	<h1>Hello world</h1>
</xsl:template>

</xsl:stylesheet>

...produces this html...

<h1 xmlns:dc="http://purl.org/dc/elements/1.1/";>Hello world</h1>

(obviously I need the dc namespace for stuff not shown for simplicity)
