Not really. You could use e.g. FXSL so you wouldn't have to write the recursive template; implementation-wise, I'd probably use e.g.

  <xsl:apply-templates select="item[1]" mode="sum"/>

in saledetails element with 

  <xsl:template match="item" mode="sum">
    <xsl:param name="grandtotal" select="0" />
    <xsl:choose>
      <xsl:when test="not(following-sibling::item)">
        <xsl:value-of select="format-number($grandtotal+(units * unit.price), '#0.00')"/>
      </xsl:when>
      <xsl:otherwise>
        <xsl:apply-templates select="following-sibling::item[1]" mode="sum">
          <xsl:with-param name="grandtotal" select="$grandtotal+(units * unit.price)"/>
        </xsl:apply-templates>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:template>

but that's just a matter of taste and doesn't make the template any more simple, really.
