Without extensions and resort to sorting, something like this should work:
(considering that the maximum of a list is either the head or the maximum of
the tail of the list)
<xsl:template name="find-max">
<xsl:param name="list"/>
<xsl:choose>
<xsl:when test="$list">
<xsl:variable name="head">
<xsl:value-of select="$list[1]"/>
</xsl:variable>
<xsl:variable name="maxTail">
<xsl:call-template name="find-max">
<xsl:with-param name="list"
select="$list[position()!=1]"/>
</xsl:call-template>
</xsl:variable>
<xsl:choose>
<xsl:when test="$head <
$maxTail">
<xsl:value-of
select="$maxTail"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of
select="$head"/>
</xsl:otherwise>
</xsl:choose>
</xsl:when>
<xsl:otherwise>0</xsl:otherwise>
</xsl:choose>
</xsl:template>

Use the maximum function from FXSL. You can customise it to accept a
comparison function as a parameter -- than you'll have a very flexible
maximum, which is not offered by XSLT 2.0 or any other library.
