Hi,

I get the error:
XPath syntax error at ... in {...get-request-parameter('quer...}:
    Cannot find a matching 1-argument function named {http://orbeon.org/oxf/xml/xforms}get-request-parameter(). Note: external function calls have been disabled

when I attempt to execute a pipeline with:
    <p:processor name="oxf:xslt">
        <p:input name="config">
            <xsl:stylesheet version="2.0">
                <xsl:template match="/">
                    <TargetURL>
                        <xsl:variable name="location" select="/Configuration/XMLDB/Location/text()"/>
                        <xsl:variable name="name" select="/Configuration/XMLDB/Name/text()"/>
                        <xsl:variable name="query" select="xxforms:get-request-parameter('query')"/>
                        <xsl:value-of select="fn:concat($location,'/',$name,'?',$query)"/>
                    </TargetURL>
                </xsl:template>
            </xsl:stylesheet>
        </p:input>
        <p:input name="data" href="#configuration"/>
        <p:output name="data" id="Target"/>
    </p:processor>

Is XPL not the correct location to retrieve the HTTP request params (should I be doing it in page-flow.xml instead?)
