Problems wits xslt processor in WSO2 - xslt

Question

In wso2 esb 4.9.0 I defined next xslt mediator:
<localEntry key="TestXslt">
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:param name="param1">
<FileList>
<File Name="b" automated="false" valid="true"/>
<File Name="c" automated="false" valid="true"/>
<File Name="d" automated="false" valid="true"/>
<File Name="e" automated="false" valid="true"/>
<File Name="f" automated="false" valid="true"/>
</FileList>
</xsl:param>
<xsl:output indent="yes"/>
<xsl:template match="/">
<xsl:for-each select="$param1/FileList/File">
<qq>TEST</qq>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
<description/>
</localEntry>
This xslt just shoul create 5 xml tags. Expected output:
<qq>TEST</qq>
<qq>TEST</qq>
<qq>TEST</qq>
<qq>TEST</qq>
<qq>TEST</qq>
But when i call this xslt mediator, my message is empty.
What i may do wrong. May be i should activate XSLT 2.0. How can i do it?

Inside WSO2, the param you pass to your TestXslt with xslt mediator become a string.
Why can't you work with the current payload message, what are you trying to do ?
If you need current message's XML payload + an other xml source (loaded from the registry for exemple) in your xsl, you can add this xml fragment inside the current message before calling xslt mediator. Use enrich mediator exemple :
<enrich>
<source clone="true" xpath="get-property('some_external_xml')"/>
<target type="body" action="child"/>
</enrich>
