This is the best I came up with when I encountered a similar problem.  It
seems pretty gross to have to sort the whole list just to find a maximum,
though.  If anyone knows a better way...

<xsl:variable name="maxmid">
   <xsl:for-each select="closing-price">
      <xsl:sort select="number(@mid)" data-type="number" order="descending"/>
      <xsl:if test="position()=1">
         <xsl:value-of select="number(@mid)"/>
      </xsl:if>
   </xsl:for-each>
</xsl:variable>
