The sitemap fragment that includes itself looks something like this:

  <?xml version="1.0"?>
  <li xmlns:petal="http://purl.org/petal/1.0/">
    <a
      href="#"
      petal:attributes="href child/URI"
      petal:content="child/Title"
    >Child Document Title</a>
    <ul
      petal:define="children child/Children"
      petal:condition="children"
      petal:repeat="child children"
    >
    <?include file="fragment.xml"?>
    </ul>
  </li>

Note that 'Children' is a method that returns a list of objects that
are already sorted.  We don't try to do the sorting in the template.
