Looking at DocBook.pm, the opening tag for a section is output when
the section is first seen, and closing tags may be output at the end
of a section for that section and containing sections. The condition
is that the section should not have subordinate sections. Sections are
closed up to the level when more sections follow on the same level.
The code is right at the end of "_convert":

    if (!($root->{'section_childs'} and scalar(@{$root->{'section_childs'}}))
        or $command_texi eq 'top') {
      $result .= "</$command>\n";
      my $current = $root;
      while ($current->{'section_up'}
             # the most up element is a virtual sectioning root element, this
             # condition avoids getting into it
             and $current->{'section_up'}->{'cmdname'}
             and !$current->{'section_next'}
             and $self->_level_corrected_section($current->{'section_up'}) ne
>'top') {
        $current = $current->{'section_up'};
        $result .= '</'.$self->_docbook_section_element($current) .">\n";
      }
    }
