http://www.docbook.org/tdg/en/html/index.html Parents These elements contain index: appendix, article, book, chapter, part, preface, sect1, sect2, sect3, sect4, sect5, section. <chapter> is in the list so what is the problem? Is that page I linked to out-of-date? The date there is 2002; if it's no longer valid is there another reference I can refer to?
