Material published with a book but following the narrative flow, for example appendices and lists of references.
Usage: Back matter typically contains supporting material such as an appendix, acknowledgment, glossary, or bibliographic reference list. In the Beta 0.2 version of this Tag Set, this element differed from the <back> element in being able to contain book parts (<book-part>).
The <sec> element can be used within the <back> to contain material that has not been explicitly named as one of the other back matter components, for example, a table that is not named explicitly as an appendix or a glossary.
<!ELEMENT book-back %book-back-model; >
