I was thinking rather vaguely about templates for sectional heading. I can think of at three style for authors to make sectional headings. As now, with section commands, with section evironments, and in a list-like manner. Templates for headings should be able of supporting classes that use a mixture of these styles. About the syntax for sectional commands, the most useful thing would be a separation of the numbering/nonumbering and table of contents options. A possible approach would be two true/false arguments, would a specification like {s o m s} be hard to remember and use? so perhaps the specification should be something like {s o m o}, the final argument defaulting to [t] for `table of contents' or [ht] for header and table of contents. (BTW this seems to show a general problem in Latex syntax when two or more indepedent optional arguments are required.) It would be useful if the templates allowed putting stuff before or after the section heading, useful for drawing rules and so on. Is this worthy of a an argument to the template. On another matter, how will collection instances be used? Will environments select a collection. Would it be useful if \begin{myenv} implictly called \UseCollection{myenv}. You could use this to prohibit sectional headings in floats, or \item outside of lists. Would this be within the expected use of collections. James
