What is the easiest way to find the max/min box numbers in each <a>?

t:\ftemp>type michele.xml
<?xml version="1.0" encoding="UTF-8"?>
<test>
  <a>
     <b>
          <box>1</box>
          <box>1</box>
     </b>
     <b>
          <box>1</box>
          <box>2</box>
          <c>
               <box>2</box>
               <box>2</box>
          </c>
     </b>
</a>
<a>
     <b>
          <box>3</box>
          <box>4</box>
          <c>
               <box>6</box>
               <box>6</box>
          </c>
          <box>5</box>
          <box>5</box>
     </b>
     <b>
          <box>5</box>
          <box>5</box>
     </b>
</a>
</test>

t:\ftemp>xslt2 michele.xml michele.xsl
1 - 2
3 - 6

t:\ftemp>type michele.xsl
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

<xsl:template match="/">
  <xsl:for-each select="test/a">
    <xsl:value-of select="min(.//box),'-',max(.//box)"/>
    <xsl:text>&#xa;</xsl:text>
  </xsl:for-each>
