Using FXSL one can write in (XSLT2):

      <xsl:if test="f:apply($operator, $lh-operand,  $rh-operand)">
              .   .   .   .   .   .   .   .
      </xsl:if>

in XSLT 1.0 this will be written as:

     <xsl:variable name="vResult" >
        <xsl:apply-templates select="$operator">
            <xsl:with-params name="arg1" select="$lh-operand"/>
            <xsl:with-params name="arg2" select="$rh-operand"/>
        </xsl:apply-templates>
     </xsl:variable>
     <xsl:if test="$vResult">
              .   .   .   .   .   .   .   .
      </xsl:if>
