[xsl] How to get rid of some namespace declarations

[Manfred Staudinger <manfred.staudinger@xxxxxxxxx>]

Hi List,

(sorry for resending because of an incorrect subject line!)

I have some input documents (from xslt 1.0, xforms), which I want to
assemble into one single document by using the xsl:collection
function. But I seem not to be able to get rid of some namespace
declarations!

Input (many of them):
<?xml version="1.0" encoding="UTF-8"?>
<openimmo xmlns="http://www.openimmo.de";
  xmlns:xf="http://www.w3.org/2002/xforms";
  xmlns:im="http://www.openimmo.de";
  xmlns:ic="http://www.example.com";>
  <ic:auftraggeber>
     <ic:name/>
  </ic:auftraggeber>
  <anbieter>
     <immobilie>
        <objektkategorie>
           <ic:objektart>wohnung</ic:objektart>
        </objektkategorie>
     </immobilie>
  </anbieter>
</openimmo>

XSLT:
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="2.0"
  xpath-default-namespace="http://www.openimmo.de";
  xmlns="http://www.openimmo.de";
  xmlns:im="http://www.openimmo.de";
  xmlns:ic="http://www.example.com";
  xmlns:xf="http://www.w3.org/2002/xforms";
  exclude-result-prefixes="im xf"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:strip-space elements="*"/>
<xsl:output method="xml" indent="yes" omit-xml-declaration="no"/>

<xsl:template name="init">
  <xsl:result-document href="../ns-test/test_2009_06_11.xml">
     <openimmo xmlns="http://www.openimmo.de";
        xmlns:ic="http://www.example.com";>
        <xsl:apply-templates
select="collection('../ns-test?select=fertig*.xml')"/>
     </openimmo>
  </xsl:result-document>
</xsl:template>

<xsl:template match="openimmo|anbieter">
  <xsl:apply-templates select="*"/>
</xsl:template>
<xsl:template match="openimmo/ic:auftraggeber"/>
<xsl:template match="immobilie[not(ic:auftraggeber)]">
  <xsl:copy>
     <xsl:copy-of select="/openimmo/ic:auftraggeber"/>
     <xsl:apply-templates select="*"/>
  </xsl:copy>
</xsl:template>
<xsl:template match="objektkategorie/ic:objektart">
     <objektart>
        <xsl:element name="{.}" namespace="http://www.openimmo.de"/>
     </objektart>
</xsl:template>
<xsl:template match="@*|node()">
  <xsl:copy>
     <xsl:apply-templates select="@*|node()"/>
  </xsl:copy>
</xsl:template>
</xsl:stylesheet>

Output (using Saxon 9.1.0.5J )
<?xml version="1.0" encoding="UTF-8"?>
<openimmo xmlns="http://www.openimmo.de";
  xmlns:ic="http://www.example.com";>
  <immobilie xmlns:xf="http://www.w3.org/2002/xforms";
     xmlns:im="http://www.openimmo.de";>
     <ic:auftraggeber>
        <ic:name/>
     </ic:auftraggeber>
     <objektkategorie>
        <objektart>
           <wohnung/>
        </objektart>
     </objektkategorie>
  </immobilie>
</openimmo>

What I would like to see:
<openimmo xmlns="http://www.openimmo.de";
  xmlns:ic="http://www.example.com";>
  <immobilie>
...
I'm sure this can be achieved, but have been running out of ideas.
