how to achieve this ?

Hello,



For a menu I have to take care that every <menu class> get a unique id.

I thought this would work :



<xsl:template match="year">
 <ul class="menu" id= "concat ('menu', @value)" >
    <li>
    <a href="#"> <xsl:value-of select="@value"/> </a>
      <ul class="acitem">
             <xsl:apply-templates select="month" />
      </ul>
     </li>
</ul>
</xsl:template>


But it don't work.

Do I have to use here <xsl:value-of> or is there a better way ?
