Colin, thanks for the pointer. I assume you mean the technique that was 
discussed in relation to the document function (note: I am using XSLT 1.0 
rather than 2). I tried this (in XML Spy for now), but got the error
'Error in function doument; Could not find external entity'

(see example XSLT below).

Is this perhaps related to to the use of data: not being supported or am I 
doing something else that is wrong ??
I will be using Xerces/Xalan in the 'real' environment (I know I should use 
this for testing also), does anyone know whether this technique will work 
with it/them ??
I haven't come across data: before. I thought that the document() function 
accepted a resolvable URI as a parameter, so does the use of data: provide a 
sort of resolver itself then ?
:-

<?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="1.0" encoding="UTF-8" indent="yes"/>

 <xsl:param name="inboundXML">
   <xsl:text>default-value</xsl:text>
 </xsl:param>

 <xsl:template match="/">

   <!-- try out the suggested technique for passing an XML string to the 
document function -->
   <xsl:variable name="myVar" 
select="document(concat('data:,text/xml',$inboundXML))"/>
   <!-- output the result -->
   <rootContainer>
       <xsl:value-of select="$inboundXML//Three"/>
   </rootContainer>

 </xsl:template>

</xsl:stylesheet>


XML sent in as param 'inboundXML' :-

<?xml version="1.0" encoding="UTF-8"?>
<Numbers>
 <Odds>
   <One>1</One>
   <Three>3</Three>
   <Five>5</Five>
 </Odds>
 <Evens>
   <Two>2</Two>
   <Four>4</Four>
   <Six>6</Six>
 </Evens>
</Numbers>

Michael>Yes. The way you pass the value depends of course on your processor 
API.
Michael, not sure what you mean, I'm using Xerces/Xalan if that helps ?

Thanks

Fraser.
