+% 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.
