namespace-alias isn't changing in output xsl

Hi,
I am trying to generate one xsl from another.
I want to change the name-space prefix from "outputxsl" to "xsl".
But it isn't working.
I am using Xalan-Java 2.
Is there a bug or am I missing s/th.

Thanks,
Gourav



My code is like :

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:outputxsl="dummy-uri">
<xsl:namespace-alias stylesheet-prefix="outputxsl" result-prefix="xsl"/>
 <xsl:output method="xml" indent="yes"/>
 <xsl:template match="/" xml:space="preserve">
  <outputxsl:stylesheet version="1.0">
   <outputxsl:template match="/Envelope">
    <xsl:apply-templates select="HyperView"/>
   </outputxsl:template>
  </outputxsl:stylesheet>
 </xsl:template>
</xsl:stylesheet>


And the output I am getting is like :
<?xml version="1.0" encoding="UTF-8"?>
  <outputxsl:stylesheet
xmlns:outputxsl="http://www.w3.org/1999/XSL/Transform"; version="1.0">
   <outputxsl:template match="/Envelope">
   </outputxsl:template>
  </outputxsl:stylesheet>
