RE: [xsl] Using keys to lookup from current stylesheet

["Michael Kay" <mhk@xxxxxxxxx>]

This works for me. If I add the template rule

    <xsl:template match="/">
      <xsl:call-template name="AcronymnStandsFor">
        <xsl:with-param name="acronym" select="'Ant'"/>
      </xsl:call-template>
    </xsl:template>

and run it under Saxon 6.5.3, with any source document, it produces

<?xml version="1.0" encoding="utf-8"?>Another Neat Tool
