XSLT 2.0 solution

  <tbody>
    <xsl:for-each-group select="results/photograph" group-by="id">
      <tr>
        <td>
          <xsl:value-of select="id"/>
        </td>
        <td>
          <xsl:value-of select="name"/>
        </td>
        <td>
          <xsl:value-of select="description"/>
        </td>
        <td>
          <xsl:value-of select="current-group()/subject" separator=", "/>
        </td>
      </tr>
    </xsl:for-each-group>
  </tbody>

See <http://www.jenitennison.com/xslt/grouping/> how to achieve this using
XSLT 1.0 and the Muenchian Method.
