% This module deals with structure: section headers, list and
% numbering and eventually cross referencing. These components are
% rather interwoven and therefore an inbetween layer is used.
% Eventually this will replace the corresponding code in core-sec,
% core-lst, core-num and core-ref.

% We collect operations that deal with things like formatting on each
% level of a number in sets. This is all handles at the \LUA\ end.
% References to such sets travel with the multipass information.
