Aha, I always like it when people produce problems that justify new XSLT
2.0 / XPath 2.0 features!

<xsl:variable name="currencies" 
  select="distinct-values(//@currency)"/>

<xsl:template match="fees/*/*">
  <tr>
    <td><xsl:value-of select="name()"/></td>
    <xsl:for-each select="$currencies">
      <td>
        <xsl:value-of select="self::*[@currency=current()]/amount"/>
      </td>
    </
  </
</

In XSLT 1.0, of course, distinct-values has to be done using keys and
Muenchian grouping.
