Problem applying XSL to XML that uses a schema

Hello,

I am trying to apply an XSL stylesheet to an XML file that uses a schema.
I will discuss first what does work.

The following is the input XML file (XML1):
<?xml version="1.0" encoding="UTF-8" ?>
<!-- MainComment1 -->
<mainelement>

   <!-- SubComment1.1 -->
   <subelement name="sub1">content</subelement>
   <!-- SubComment1.2 -->

   <!-- SubComment2.1 -->
   <subelement name="sub2">content</subelement>
   <!-- SubComment2.2 -->

</mainelement>
<!-- MainComment2 -->


The following is the xsl I have so far (XSL1):
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.1" indent="yes" />

<xsl:template match="comment()">
  <xsl:comment><xsl:value-of select="."/></xsl:comment>
</xsl:template>

<xsl:template match="subelement|@*">
    <xsl:copy>
        <xsl:apply-templates select="node()|@*"/>
    </xsl:copy>
</xsl:template>

<xsl:template match="mainelement|@*">
  <xsl:copy>
      <xsl:apply-templates select="node()|@*"/>

      <xsl:comment >NewSubComment1.1</xsl:comment>
      <xsl:text>&#xA;</xsl:text>
      <subelement name="newsub">content</subelement>
      <xsl:comment >NewSubComment1.2</xsl:comment>
  </xsl:copy>
</xsl:template>
</xsl:stylesheet>


The following is the output from applying XSL1 to XML1 (OUTPUT1):
<?xml version="1.0" encoding="UTF-8"?>
<!-- MainComment1 -->
<mainelement>

   <!-- SubComment1.1 -->
   <subelement name="sub1">content</subelement>
   <!-- SubComment1.2 -->

   <!-- SubComment2.1 -->
   <subelement name="sub2">content</subelement>
   <!-- SubComment2.2 -->

<!--NewSubComment1.1-->
<subelement name="newsub">content</subelement>
<!--NewSubComment1.2-->

</mainelement>
<!-- MainComment2 -->


This is exactly what I want without the schema (OUTPUT1).  The problem is when
the XML file uses a schema which is my real world problem.

The following is the input XML file that uses the schema (XML2):
<?xml version="1.0" encoding="UTF-8" ?>
<!-- MainComment1 -->
<mainelement
    xmlns="http://www.mydomain.com/mainelement"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.mydomain.com/mainelement
file:///C:/schemas/mainelement.xsd">

   <!-- SubComment1.1 -->
   <subelement name="sub1">content</subelement>
   <!-- SubComment1.2 -->

   <!-- SubComment2.1 -->
   <subelement name="sub2">content</subelement>
   <!-- SubComment2.2 -->

</mainelement>
<!-- MainComment2 -->


When I apply XSL1 to XML2 I get the following output (OUTPUT2):
<?xml version="1.0" encoding="UTF-8"?>
<!-- MainComment1 -->

   <!-- SubComment1.1 -->
   content
   <!-- SubComment1.2 -->

   <!-- SubComment2.1 -->
   content
   <!-- SubComment2.2 -->

<!-- MainComment2 -->





OUTPUT2 is clearly not what I want.  I want the exact same output as OUTPUT1
except with the schema location and xmlns etc.  The following is the desired
output (DESIREDOUTPUT):
<?xml version="1.0" encoding="UTF-8"?>
<!-- MainComment1 -->
<mainelement
    xmlns="http://www.mydomain.com/mainelement"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.mydomain.com/mainelement
file:///C:/schemas/mainelement.xsd">

   <!-- SubComment1.1 -->
   <subelement name="sub1">content</subelement>
   <!-- SubComment1.2 -->

   <!-- SubComment2.1 -->
   <subelement name="sub2">content</subelement>
   <!-- SubComment2.2 -->

<!--NewSubComment1.1-->
<subelement name="newsub">content</subelement>
<!--NewSubComment1.2-->
</mainelement>
<!-- MainComment2 -->





Can anyone help me understand how to modify my XSL1 to create the DESIREDOUTPUT?
 Any help would be greatly appreciated.  I have been trying to make this work
for days!


Thanks,

Tim
