Check out exslt.org.

<xsl:template match="values">
  <xsl:choose xmlns:math="http://exslt.org/math">
    <xsl:when test="function-available('math:max')">
      <xsl:value-of select="math:max(value)"/>
    </xsl:when>
    <xsl:otherwise>
      <xsl:choose>
        <xsl:when test="not(value)">NaN</xsl:when>
        <xsl:otherwise>
          <xsl:for-each select="value">
            <xsl:sort data-type="number" order="descending" />
            <xsl:if test="position() = 1">
               <xsl:value-of select="number(.)" />
            </xsl:if>
          </xsl:for-each>
        </xsl:otherwise>
      </xsl:choose>
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>
