A recursive template could do this.

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
 <xsl:template match="/values" >
  <xsl:call-template name="getMaxValue">
   <xsl:with-param name="count" select="count(value)" />
  </xsl:call-template>
 </xsl:template>
 
 <!-- Start of the recursive template -->
 <xsl:template name="getMaxValue">
  <xsl:param name="count"/>
  <xsl:param name="maxValue" />
  <xsl:variable name="curValue" select="value[position() = $count]" />
  <xsl:choose>
   <xsl:when test="$count != 1">
    <xsl:variable name="newMaxValue">
     <!-- If the current value is greater than the previous maxValue, set the newMaxValue to the 'new max value' -->
     <xsl:choose>
      <xsl:when test="$curValue &gt; $maxValue">
       <xsl:value-of select="$curValue"/>
      </xsl:when>
      <xsl:otherwise>
       <xsl:value-of select="$maxValue"/>
      </xsl:otherwise>
     </xsl:choose>
    </xsl:variable>
    <xsl:call-template name="getMaxValue">
     <xsl:with-param name="count" select="$count - 1"/>
     <xsl:with-param name="maxValue" select="$newMaxValue"/>
    </xsl:call-template>
   </xsl:when>
   <xsl:otherwise>
    <xsl:value-of select="$maxValue" />
   </xsl:otherwise>
  </xsl:choose>
 </xsl:template>
</xsl:stylesheet>

HTH,
