tables are problematic, difficult to reconstitute instruction, check

metadata, move to top? and work on

footnotes, different types, asterisk, also do you want to have separate
paragraphs, or breaks within one block?

where no ocn appropriately use ~# or -# or indeed 1~name-

comments in document, what to do about them, not sure they are currently
retained in dal, could be quite valuable to keep
