But apparently Hutchinson based his guess in three main points: i) Server statistics over last 5 years with its TtH and TtM, ii) Technical (annoyances) issues of MathML, iii) History of the mathematical markup. Whereas similar claims from MathML folks (waiting magical spread of MathML on the Internet) appear to be based in faith. > I could quibble over how > big a niche might be, but I am not clear how MathML could > 'take over web mathematics publishing' at the present stage of > web technology.

Whereas one can see an increasing interest in CSS, including printing of books, there is not such one increasing in MathML. At contrary, apparently nobody want print using MathML and there is a return to TeX bassed systems (MathML to TeX conversors). E.g. last MSIE adds a better support for CSS, whereas continues ignoring MathML native support. > Where I questioned the attribution to Hutchinson was for > the phrasing > >> we abandon the MathML approach, encourage to all us users, >> collaborators, and visitors to abandon MathML, > > but I now see that perhaps you intended to convey in > http://lists.w3.org/Archives/Public/www-math/2006Jul/0028.html > not that sense of attribution to IH, but that you wished to correct your > typo by > us users ==> our users Now I understand the confusion.

Ok? No, it was an example of how the same CSS techniques can be reused in HTML-XML-SGML (note that CSS-like techniques could be implemented in a DSSSL engine thanks to similarity with XSL-FO). The point was that CSS techniques are more versatile than p-MathML. > Obviously one can work with other markup than valid XML. > It just does not seem to me a very good idea in this > context today.

Agree with requirement on consonancy with other specs but I cannot agree with the history. It would be not the first time is claimed that the MathML WG reinvented the wheel whereas ignored other specs. Hakon Wium Lie, from w3c CSS WG, wrote last month, <blockquote> Historically, it's a common mistake to develop markup systems without giving much thought to presentation. [...] Given that CSS existed when MathML was created, I think the developers made a mistake by not creating a markup language that could be presented using existing CSS properties. </blockquote> > All the best, > > Patrick Juan R.
