<xsl:output method="text" version="1.0" encoding="ISO-8859-1"
indent="yes" omit-xml-declaration="yes" />

<xsl:template match="/">

<xsl:call-template   name="test_redirect">
 <xsl:with-param name="pcontenu" select="'aaaaaaaaaaaaaa'"/>
</xsl:call-template>

<xsl:call-template   name="test_redirect">
 <xsl:with-param name="pcontenu" select="'cccccccccccccccccc'"/>
</xsl:call-template>

</xsl:template>


<xsl:template   name="test_redirect">
<xsl:param name="pcontenu" select="nn"/>
