A numbered thesis lost every "1.", "2.1.4" and "A." on import: the outline
definition was read as a list wrapping headings and dropped. It is now a
document-level definition on the style sheet (format, prefix, suffix,
display-levels, start per level), drawn by CSS counters that reset down the
levels, and carried by both formats — ODF's text:outline-style, Word's
multilevel numbering bound to the heading styles. The contents rows count the
same way, since no text walk can read a CSS counter.
