Front matter, body matter and rear matter (see <http://www.daisy.org/z3986/structure/SG-DAISY3/part1.html#auto_0008>) are currently supported by inserting a section called "BodyMatterStart" between the front matter and the body matter, and a section called "RearMatterStart" between the body matter and the read matter.
odt2braille uses a more elegant approach:
The front matter corresponds to a section called "PreliminaryPages"; the title page can the be a subsection called "TitlePage".
The body matter can optionally contain sections called "Volume1", "Volume2" etcetera, but body matter sections are not required.
The rear matter can be created by using sections called "Supplement1", "Supplement2", etcetera.
Making section handling consistent between odt2daisy and odt2braille would benefit DAISY & Braille production centres that want to use ODF as a single source for both DAISY and Braille.
