% Notes
% ~~~~~
%
% The following tags are used:
% ttl@ : the generic tag used through the style
% ttlh@ : a shape definition
% ttlf@ : a macro containing the title format
% ttls@ : id. the title space
% ttlp@ : page key related macros
% ttll@ : level number
%
% The ttlf@ and ttls@ contains data in the form {..}{..}.
% Perhaps in future releases they should be converted
% to a prop-like list, similar to that proposed by the
% latex team.
%
% Admittedly, the current implementation seems too
% complicated, but that's necessary in order to provide
% certain compatibility with the sections as defined by the
% used class. Other packages opt for providing the sections
% as defined by standard classes ignoring the class; for
% instance sectsty which does a simple task in a simple and
% nice way. However, that was not my goal.
