XSLT Function insert-before not recognized

Question

I'm creating a xslt file with baseX but the function insert-before is not recognized. It is a standard function (you can see it here http://www.w3schools.com/xpath/xpath_functions.asp) and I also tried to declare the namespace fn like this

xmlns:fn="http://www.w3.org/2005/xpath-functions"

and then call the function with fn:insert-before but it still doesn't work. This is a sample of my code

<xsl:call-template name="temp">
   ....
   <xsl:with-param name="array" select="fn:insert-before($array,$count+1,$succ)"/>
   ...
</xsl:call-template>

Any ideas?

The BaseX documentation at

http://docs.basex.org/wiki/XSLT_Module

states that it uses the default JDK 1.5 XSLT engine by default. This only supports XSLT 1.0. The same page explains how to configure it to run with an XSLT 2.0 engine such as Saxon.
