missing xsl: before schemaLocation in the result xml

I am converting xml to xml by using xslt. For some reason, my result
missed "xsl:" before schemaLocation. Could you please help me find
what's wrong?



My xml file starts with

<?xml version="1.0" encoding="UTF-8"?>
<blueprint base_time="1998-11-05T12:00:00" duration_seconds="12"
tail_seconds="0.25" version="0.10"
xsi:schemaLocation="http://directv.com/bitstreams/blueprint
C:/TRex-Dev/Trunk/Projects/MODEL/bde.model.xml/blueprint/xsd/Blueprint.x
sd" xmlns="http://directv.com/bitstreams/blueprint"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:abe="http://directv.com/bitstreams/abe"
xmlns:bp="http://directv.com/bitstreams/blueprint"
xmlns:rex="http://directv.com/bitstreams/rexatron">


My xslt file starts with
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0 "
xmlns="http://directv.com/bitstreams/blueprint"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:xdt="http://www.w3.org/2005/xpath-datatypes"
exclude-result-prefixes="xs xdt">

And I use imported file copy.xslt during procession.
<?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"/>

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

</xsl:stylesheet>



My result xml file:
<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns:bp="http://directv.com/bitstreams/blueprint"
           xmlns="http://directv.com/bitstreams/blueprint"
           xmlns:rex="http://directv.com/bitstreams/rexatron"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xmlns:abe="http://directv.com/bitstreams/abe"
           base_time="1998-11-05T12:00:00"
           duration_seconds="12"
           tail_seconds="0.25"
           version="0.10"
           schemaLocation="http://directv.com/bitstreams/blueprint
C:/TRex-Dev/Trunk/Projects/MODEL/bde.model.xml/blueprint/xsd/Blueprint.x
sd">


Thanks,
