xml transformation

[Cringer]

I've got an Ajax request that creates some xml from a Progress db. I then perform an xsl transformation on it to create an HTML select to plonk on the screen. I pass the selected item through to the xslt as a parameter so that I can set the relevant option as selected. This all works brilliantly for a single option select. The trouble is that now I need to convert it to a multiple option select and thus my parameter is a comma delimited list of selected values. I'm not sure what I need to do to achieve this. Any ideas?

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">


<xsl:param name="SelectID" /> 
<xsl:param name="VarietyListNumber" />


<xsl:output method="html" media-type="text/html" cdata-section-elements="script" omit-xml-declaration="yes" standalone="yes"/>
    <xsl:template match="/">
        <xsl:choose>
            <xsl:when test="count(/finvlin/finvlinRow) = 0">
                                <xsl:element name="select">

Not to worry - I've deferred the selection to a piece of javascript that runs after the xslt has been applied.
