Another problem with namespaces and XSL

Hello everybody,

I'm having another problem with namespaces and XSL.
I'm making a stylesheet that generate another stylesheet.
I want to generate the "desired XML output" of the "son" stylesheet,
that is generated by "mother" one.
The problem is:
* In the "son" stylesheet, is shown
xmlns:axsl="http://www.w3.org/1999/XSL/TransformAlias" in the axsl:key
and axsl:value-of elements. Why this happens? I don't desire this. If
this isn't printed in output, the desired XML output is generated.
I'm sending some examples of this stylesheets. The input for the
stylesheets is the XML file above.
Regards,

"Mother" stylesheet:

<xsl:stylesheet version="1.0"

        </root>
      </axsl:template>
    </axsl:stylesheet>
  </xsl:template>

Generated "son" stylesheet:

<axsl:stylesheet xmlns:axsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

select="key('tCategories', 1)/CategoryName"/>
    </root>
  </axsl:template>
</axsl:stylesheet>

Desired "son" stylesheet (whitout
xmlns:axsl="http://www.w3.org/1999/XSL/TransformAlias"):

<axsl:stylesheet xmlns:axsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xlink="http://www.w3.org/1999/xlink" version="1.0">
  <axsl:output method="xml" omit-xml-declaration="no"
encoding="iso-8859-1" standalone="yes" indent="yes"/>
  <axsl:key name="tCategories" match="Categories" use="./CategoryID"/>
  <axsl:template match="text()" priority="-1"/>
  <axsl:template match="/">
    <root>
      <node>
        <ref xlink:href="#products"/>
      </node>
      <axsl:value-of select="key('tCategories', 1)/CategoryName"/>
    </root>
  </axsl:template>
</axsl:stylesheet>

Generated XML output:

<root xmlns:xlink="http://www.w3.org/1999/xlink">
  <node>
    <ref xlink:href="#products"/>
  </node>
  <axsl:value-of xmlns:axsl="http://www.w3.org/1999/XSL/TransformAlias"
select="key('tCategories', 1)/CategoryName"/>
</root>

Desired XML output:

<root xmlns="http://www.topicmaps.org/xtm/1.0/"
xmlns:xlink="http://www.w3.org/1999/xlink">
  <node>
    <ref xlink:href="#products"/>
