empty HTML files for set, book, part elements

[Robert Pasternak <rp.info@gmail.com>]

Dear All

My book definition looks like that:


<set>
  <set>
    <title>set1</title>
    <book>
      <title>book1</title>
      <part>
        <title>part1</title>
        <xi:include href="article1.xml"/>
        <xi:include href="article2.xml"/>
      </part>
    </book>
    <book>
      <title>book2</title>
      <part>
        <title>part2</title>
        <xi:include href="article3.xml"/>
        <xi:include href="article4.xml"/>
      </part>
     ...


I use profile-chunk.xsl with some customization. Please note that
included xml files start with the article element. Now, for each set,
book, part element the transform produces an html file, basically an
empty file with some navigation information. Is it possible to block
that behavior so that html files are only produced for article
elements?

Thanks,
Robert
