EPUB3: missing some meta data

Hi Bob,

working with the latest Beta2 of the EPUB3 extensions I'm missing some
metadata in the resulting EPUB file (which are present if working with
the original EPUB2 XSL stylesheets):

  <bookinfo id="bookinfo">
    <title>Some Title</title>
    <subtitle>Subtitle</subtitle>
    <author>
      <firstname>Firstname</firstname><surname>Surname</surname>
    </author>

    <revhistory>
      <revision>
	<revnumber>0.0.1</revnumber>
	<date>2011-09-25</date>
        <revremark>Remark</revremark>
      </revision>
    </revhistory>

    <!-- MISSING -->
    <copyright>
      <year>2001 &dash; 2011</year>
      <holder>John Doe</holder>
    </copyright>

    <!-- MISSING -->
    <publisher><publishername>Private person</publishername></publisher>

    <!-- MISSING -->
    <subjectset>
      <subject>

      </subject>
      <subject>

      </subject>
    </subjectset>

  </bookinfo>
