Hi, We're curious what math symbols users actually use. There are for instance all kind of variations on '<' and '>' and the quesiton is: how should we group them and are they used differently in different contexts. Traditionally tex sort of groups according to spacing related classes but we are (1) mor egranular than that and (2) like to organize symbols (and related commands) into meaning related groups. The fact that for instance mathml and openmath only groups a small selection is kind of puzzling because it means that only a handful is considered useful while on the other han dwe have plenty in unicode and fonts (of course multiple usage and overloads complicate matters). We'd like to sort out some of the mess that the tex community accumulated over decades and are not that bound to conventions, more to a well organized whole, Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
