Just to organise the discussion a bit, perhaps it should proceed in 5 steps (perhaps partially simultaneously): 1. Agree on WHAT INFORMATION needs to be provided 2. Agree on HOW IT SHOULD BE DIVIDED UP (all information about one author grouped together, all addresses together, leave both possibilities open,...) 3. Agree on a SYNTAX (keywords or not,...) and requirements on how they are to be interpreted by various .cls (unused things must be understood but annoyed,...) 4. Additional items: should `unwanted' commands be redefined to give error messages (to prevent the author attempting visual formatting, for example, or using \thanks,...),... 5.
