Mark, I welcome your comment that your interest in MathML is largely because it is embedded in CellML. CellML does seem to have quite wide support. I've wondered for some time what difficulties users of CellML may have found with aspects of MathML, and if there are suggestions from that user community that can be used to improve MathML as it goes toward a new revision (the WG that can write such a revision has just ben chartered). I'd say you should feel free to comment, and to ask others using CellML to do the same. The CML for chemistry also thought of MathML as a given with which to work, as did, say, MatML for materials and others. It would be great, I think, if anyone who can comment from experience on what such markups need from a MathML will do so. You are right that, in effect, this is a MathML list nowadays. But Juan is technically correct that it was conceived to discuss math on the Web more generally. Perhaps the present situation may be summed up by saying 'www-math is a place to discuss the W3C's efforts to facilitate communicating math on the Web'. So naturally the messages are mostly about MathML and its interactions with other W3C technologies. It has to be admitted that Juan R and George C are proposing use of W3C specs (XML and CSS). However, it seems to be clear that they are proposing that yet another markup language for math be specified, as is implicit in George's Universal Math Style Sheet (cf., say, the new elements <ker> <sat> </line/> <wrap/>). In addition, they seem to be assuring us of the effectiveness, and wide correct future deployment of enhancements to CSS that have yet to be made. We probably all dearly hope for that. Some great advantages of starting again from scratch will need to be more explicitly demonstrated for me personally to be inclined to do so. However, it is my opinion that any good examples of problems and solutions with markup and rendering of math and formulas should be useful to the W3C Math WG. The WG does have an 'installed base' to consider as Robert Miner has clearly pointed out. They will be helped by any good solutions that can be adopted.
