xsl include

Hello,
I´m trying to include some xsl into one xsl... something like this:

 <xsl:choose>
          <xsl:when test="$MyVariable = 1">
               <xsl:include href="xslinclude.xsl">
          </xsl:when>
          <xsl:otherwise>
              <xsl:include href="xslinclude.xsl">
           </xsl:otherwise>
 </xsl:choose>

I get error with this... anybody knows how to solve this???
Thanks
