  The common case is either no <conference> elements, or one with a single
  title (JConf/121):
    <date-history received="2008-06-30" published-online="2008-07-31"/>
    <conference>
      <conference-title>JOINT 21ST AIRAPT AND 45TH EHPRG INTERNATIONAL CONFERENCE ON HIGH PRESSURE SCIENCE AND TECHNOLOGY</conference-title>
      <conference-date start="2007-09-17" end="2007-09-21">17-21 September 2007</conference-date>
      <conference-location country="it">Catania, Italy</conference-location>
      <conference-editors>
        <conference-editor order="given-surname">
          <given>G G N</given>
          <surname>Angilella</surname>
        </conference-editor>
        <conference-editor order="given-surname">
          <given>R</given>
          <surname>Pucci</surname>
        </conference-editor>
        <conference-editor order="given-surname">

        </conference-editor>
      </conference-editors>
      <conference-info>This volume has been divided into 16 subject related parts.</conference-info>
    </conference>
  
  However, there are a few cases with multiple simultaneous co-located
  conferences (JConf/100) where a single conference may have multiple titles:
    <date-history received="2008-02-22" published-online="2008-03-27"/>
    <conference>
      <conference-title>17TH INTERNATIONAL VACUUM CONGRESS (IVC-17)</conference-title>
      <conference-title>13TH INTERNATIONAL CONFERENCE ON SURFACE SCIENCE, (ICSS-13)</conference-title>
      <conference-title>INTERNATIONAL CONFERENCE ON NANOSCIENCE AND TECHNOLOGY (ICN+T 2007)</conference-title>
      <conference-date start="2007-07-02" end="2007-07-06">2-6 July 2007</conference-date>
      <conference-location country="se">Stockholm, Sweden</conference-location>
      <conference-info>This volume has been divided into nine subject related parts.</conference-info>
    </conference>

  There are also volumes which combine multiple disparate but related
  conferences (JConf/280) which have multiple <conference> elements, each with
  its own title, date and location:
    <date-history received="2011-02-01"/>
    <conference>
      <conference-title>2009 Young Researchers Meeting in Rome</conference-title>
      <conference-date start="2009-07-21">21 July 2009</conference-date>
      <conference-location country="it">University of Rome "Tor Vergata"</conference-location>
    </conference>
    <conference>
      <conference-title>2010 Young Researchers Meeting in Rome</conference-title>
      <conference-date start="2010-02-09">9 February 2010</conference-date>
      <conference-location country="it">University of Rome "La Sapienza", Italy</conference-location>
    </conference>
