I agree. Thanks David there was a double declaration.

I've managed to get it going.

Fix the header as follows.

<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"
   xmlns:saxon="http://saxon.sf.net/"
   xmlns:ns3="http://www.w3.org/2001/XMLSchema"
   version="2.0"
   exclude-result-prefixes="xsl ns3 calypso xsi saxon"
   >

Then output as follows

               <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="$message/ISIN"/>
               </xsl:element>

ie. Use element plus attribute and makes sure the names are correct.

Thanks

Nick
