> Please don't speak of MathML, ok? ;) Ah. When I'm not being `latex3 project' I do, these days, have another hat which says `W3C Math (MathML) Committee member'.

What people do now (ie before any of the browsers have native MathML support) is typically make most of the mathematics in their HTML documents as inlined GIF images. MathML only looks large because you make the mistake of looking at it. GIF is much larger but you don't (unless you are Sebastian) try and read it bit by bit in a binary editor. > I will freely choose my editor, ranging from things like emacs, to > smaller editors like joe or my favourite one in DOS (!), i.e., Turbo > Pascal (!). I tend to use emacs for everything, in case you hadn't noticed emacs users are a minority. Some of us will continue to use that kind of interface, but MathML offers the hope of using systems like Scientific Word, and even Microsoft Word via the MathType/Equation Editor thing and getting something useable out the back, not some obscure rtf extension (out of MS Word), or LaTeX (out of Scientific word) which is even more obscure to many people... There is a very large class of users who would greatly benefit from being able to enter essentially school or undergraduate level mathematics in a wysywig fashion and have the mathematics being portable from their wysywig editor into tex for decent mathematical typesetting, and (soon?) into browsers for online display, but also symbolic algebra systems such as Mathematica, or Maple (oh I believe Axiom is jolly good too:-). For more complete control over the semantics you probably need something like OpenMath layered over MathML, but that is even more verbose, and not really relevant to the typesetting aspects of this list. There will (perhaps? Sebastian would probably say will not) be a future for a `tex like' syntax for document markup, and mathematical markup in particular, but whatever happens there in the `traditional' tex world, there will _certainly_ be a very large number of documents marked up to some Mathematics SGML/XML dtd (MathML being the current favourite, but any other one is likely to look equally verbose and alien to a TeX user). (La)TeX can play a role in typesetting these documents to its normal high standards of mathematical typesetting. Just because some people are working in this area does not mean that latex is necessarily abandoning its traditional users, or that they have to use any such XML system. Although perhaps in the end the rather arcane XML syntax may seem like a price worth paying _if_ it achieves the goals of integration with symbolic algebra packages and on line browsers. David
