-- A Paragraph is composed of a sequence of Text_Block, File, Graphic,

-- NEW_LEVEL increments to the next section level and sets that
-- level's section number to 0. Nothing is output to the document.
-- NEXT_SUB_PARAGRAPH causes the current level's (rightmost) section

-- section level and sets that level's section number to 1.
-- END_LEVEL decrements the section level.
-- xxx_LEVEL operations are used for setting up a loop which uses
-- NEXT_SUB_PARAGRAPH to generate nested sections.

-- (Roman numerals or letters).
-- Appendix numbers (NUMBERED) must be in increasing order.
