(: Section: 1.2.4.5 Q5  Make a flat list of the section elements in Book1.  In place of its original attributes, each section element  should have two attributes, containing the title of the section  and the number of figures immediately contained in the section. :)



<section_list>
  {
    for $s in doc("book.xml")//section
    let $f := $s/figure
    return
        <section title="{ $s/title/text() }" figcount="{ count($f) }"/>
  }
</section_list>
