RE: Removing empty namespace definition from an element

The basic message with problems like this is to make sure that your elements
are in the right namespace; if they are, the namespace declarations will
look after themselves. You have the unwanted namespace declaration because
you created the element in the wrong namespace.

If you use xsl:element to create an element, use the namespace attribute to
define what namespace you want it to be in. But in this case, you could
equally well use a literal result element.

Subject: [xsl] Removing empty namespace definition from an element

I've learned quite a lot since my last post.  I've managed to 
rework my
XSL file in accordance with Mike Kay's suggestions.  I only have one
obstacle left in my transformation.

Here is the beginning of my input XML:

<?xml version="1.0" encoding="utf-16"?>
<sequence version="1" description="Deploy Server"
command="DeployServer.xml"
xmlns="http://schemas.microsoft.com/ads/2003/sequence";>
  <task description="Launch Image Deployment Tool" doesReboot="false">
    <command target="controller">C:\Patches\Tools\dpIDT.vbs</command>
    <parameters>
      <parameter>$device.system.name$</parameter>
      <parameter>_osName_</parameter>
    </parameters>
  </task>


And here is part of the relevant XSL:

xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
 
xmlns:ads="http://schemas.microsoft.com/ads/2003/sequence";
                version="1.0">

  <xsl:output method="xml" indent="yes"/>
  <xsl:variable name="osName" select="'WIN2K3'"/>

  <xsl:template match="/">
    <xsl:apply-templates/>
  </xsl:template>

  <xsl:template match="ads:parameter[.='_osName_']">
    <xsl:element name="parameter"><xsl:value-of
select="$osName"/></xsl:element>
  </xsl:template>


Now the match works just fine, the issue is the element 
parameter looks
like this in the output:

<task description="Launch Image Deployment Tool" doesReboot="false">
<command target="controller">C:\Patches\Tools\dpIDT.vbs</command>
<parameters>
<parameter>$device.system.name$</parameter>
<parameter xmlns="">WIN2K3</parameter>
</parameters>
</task>

My interpreter does not like the empty namespace declaration. 
 The only
way I have figured out how to get it to not show is by using this as a
template instead:

  <xsl:template match="ads:parameter[.='_osName_']">
    <xsl:text 
disable-output-escaping="yes">&lt;parameter&gt;</xsl:text>
        <xsl:value-of select="$osName"/>
    <xsl:text
disable-output-escaping="yes">&lt;/parameter&gt;</xsl:text>
  </xsl:template>


And that's REAL UGLY!


Is there a better?  A real way, using XSLT logic?
