No. Sorry, I was discussing it hypothetically. In fact I *don't* think that HTML+ should deal with the question of dynamically extending the DTD. HTML+ would *be* a DTD. HTML+ is a communication standard. If you want a private DTD which has a gioven mapping onto HTML+ (eg <crazy> onto <em>) then do the mapping on the fly before transmission if your peer accepts HTML+ but not yoru own DTD. It is a separate question (from HTML+ design) as to whether to allow new things to be defined on the fly. We can tease out usefully - Definition of style sheets for new or old DTDs to map DTDs onto presentation - Extendable object-oriented systems I am not convinced that persuing SGML declarations and architecural forms will give us sufficient power to handle the general extension of our system, and we should look at other things (ez and andrew for example) to define something much more powerful. But a style sheet task force would be useful, as it operates in a much more well-defined way. Tim
