I thought I had a solution to my namespace problem, but on
investigation I haven't
On further investigation, I haven't got it going, so I've produced a
cut down version
showing the problem

here is a test xml file

===================
<?xml version="1.0" encoding="UTF-8"?>
<bonds>
   <isin>123</isin>
   <isin>456</isin>
   <isin>789</isin>
</bonds>
===================


Here is the xslt cut down
===================
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
   xmlns:calypso="http://www.calypso.com/xml"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   version="2.0">

   <xsl:output method="xml" indent="yes"/>

   <xsl:template match="/">
       <bonds>
           <xsl:for-each select="//isin">
           <bond>
               <calypso:secCode>
                   <calypso:name>ISIN</calypso:name>
                   <xsl:element name="calypso:value">
                       <xsl:attribute
name="xsi:type">ns3:string</xsl:attribute>
                       <xsl:attribute
name="ns3">http://www.w3.org/2001/XMLSchema</xsl:attribute>
                       <xsl:value-of select="."/>
                   </xsl:element>
               </calypso:secCode>
           </bond>
       </xsl:for-each>
       </bonds>
   </xsl:template>
</xsl:stylesheet>

===================

Here is the output

===================
<?xml version="1.0" encoding="UTF-8"?>
<bonds xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xmlns:calypso="http://www.calypso.com/xml">
  <bond>
     <calypso:secCode>
        <calypso:name>ISIN</calypso:name>
        <calypso:value xsi:type="ns3:string"
ns3="http://www.w3.org/2001/XMLSchema">123</calypso:value>
     </calypso:secCode>
  </bond>
  <bond>
     <calypso:secCode>
        <calypso:name>ISIN</calypso:name>
        <calypso:value xsi:type="ns3:string"
ns3="http://www.w3.org/2001/XMLSchema">456</calypso:value>
     </calypso:secCode>
  </bond>
  <bond>
     <calypso:secCode>
        <calypso:name>ISIN</calypso:name>
        <calypso:value xsi:type="ns3:string"
ns3="http://www.w3.org/2001/XMLSchema">789</calypso:value>
     </calypso:secCode>
  </bond>
</bonds>
===================

Here is the desired output

===================
<?xml version="1.0" encoding="UTF-8"?>
<bonds xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xmlns:calypso="http://www.calypso.com/xml">
  <bond>
     <calypso:secCode>
        <calypso:name>ISIN</calypso:name>
        <calypso:value xsi:type="ns3:string"
xmlns:ns3="http://www.w3.org/2001/XMLSchema">123</calypso:value>
     </calypso:secCode>
  </bond>
  <bond>
     <calypso:secCode>
        <calypso:name>ISIN</calypso:name>
        <calypso:value xsi:type="ns3:string"
xmlns:ns3="http://www.w3.org/2001/XMLSchema">456</calypso:value>
     </calypso:secCode>
  </bond>
  <bond>
     <calypso:secCode>
        <calypso:name>ISIN</calypso:name>
        <calypso:value xsi:type="ns3:string"
xmlns:ns3="http://www.w3.org/2001/XMLSchema">789</calypso:value>
     </calypso:secCode>
  </bond>
</bonds>
===================


The difference is that I need

ns3="http://www.w3.org/2001/XMLSchema"

output as

xmlns:ns3="http://www.w3.org/2001/XMLSchema"


Any ideas?
