[xsl] Is this legal?

Hi there --

I have an apply-templates that is not working as expected. I want to select
all PRODUCT elements with at least one TRACK that has a LAST_UPDATE element
that is newer than the passed in 'trimDate' parameter.

I expect the external function jString:compareTo() to be called for each
TRACK Element. It is called only once for the first TRACK. 

    <xsl:template match="/" >        
        <xsl:message>Filtering tracks earlier than <xsl:value-of
select="$trimDate" /></xsl:message>
        <PRODUCT_LIST PACKAGER="DWS" >
        <xsl:apply-templates
select="PRODUCT_LIST/PRODUCT[jString:compareTo($trimDate,
rioport:formatDate(./PRODUCT_DETAILS/TRACK/LAST_UPDATE)) &lt; 0]" />
        </PRODUCT_LIST>
    </xsl:template>
