TB is a triple bond. <.> is a dotted (coordinated) bond. "Emphasis" italics have a * mark. [#] footnotes moved to EOParagraphs but NOT renumbered. (They are numbered "a" or "b" when two pages of notes are together.) Comments and guessed at characters in {braces} need stripped/fixed. Greek letters are encoded in <gr > brackets, and the letters are based on Adobe's Symbol font.
