[xsl] Why is an empty xmlns="" added to child when I add namespace to parent?

[Alex Muir <amuir@xxxxxxxxxx>]

Hi,

The following code adds a namespace to the mediawiki element and a
copyAll I import copies the other elements

 <xsl:import href="copyAll.xsl"/>
 <xsl:template match="mediawiki">
    <mediawiki  xmlns="http://www.mediawiki.org/xml/export-0.4/";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://www.mediawiki.org/xml/export-0.4/
http://www.mediawiki.org/xml/export-0.4.xsd"; version="0.4"
xml:lang="en">
      <xsl:apply-templates/>
    </mediawiki>
  </xsl:template>

However in the result the child element <page> gets a blank xmlns=""
attribute added..... Why?

<mediawiki xmlns="http://www.mediawiki.org/xml/export-0.4/";
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
  xsi:schemaLocation="http://www.mediawiki.org/xml/export-0.4/
http://www.mediawiki.org/xml/export-0.4.xsd";
  version="0.4" xml:lang="en">
  <page xmlns="">
