BUT REVTeX is not LaTeX and that is reason that Physical Review list contains "REVTeX (preferred), LaTeX (not preferred)..." >> That TeX-LaTeX is not >> sufficient for the web is also recogined even by TeX gurus as David >> Carlisle [1]. > > Note that I have never advocated putting TeX directly on the web.

Note that a^b can be converted to a<sup>b</sup> with unusual easiness whereas the conversion to <msup>a b</msup> is much more difficult; really so difficult that today conversors to MathML often offer incorrect outputs of trivial TeX mathematical fragments of above class. The problem is that MathML encodes bases as childs of a script element, whereas bases are not explicitely marked in TeX sources, therefore the conversor may go backward in the TeX source imaginating what is the base. That problem disappear in George approach. See his blog (was cited here) for an experimental XSLT TeX --> Maiden. He did in a pair of days; others have failed even after several years when trying to use MathML. Take the case of Distler blog like example. It has been unable to encode ds^2. In the past encoded like 2s ds, some days ago he changed, but the code generated continues being wrong. >> Do you know that LaTeX3 is moving towards SGML/HTML model of >> publications in some aspects? > > Excellent.

Reason that LaTeX is focusing to SGML/HTML world appears clear to me: popularity and solidness. SGML/HTML is more broadly used than TeX based languages and SGML is much more potent. Therefore, embracing certain compatibility with popular languages is promoting the survival of LaTeX in the future. LaTeX3 project will embrace a new syntax (I do not know details) and further changes. Therefore, I would not call that "small steps". Active TeX was an early attempt to join TeX to HTML and SGML. Active TeX also introduced a new syntax without "\" without "{" and without "}". It was called the "dot syntax". I would not call those "small steps". However current HTML5 proposal is a natural continuation of HTML, using same basic rules and guidelines that worked very well in HTML during years. Moreover a TeX user would not find HTML Math completely understandable \frac{b}{2} ==> <frac><num>b</num><den>2</den></frac> {a \over 3} ==> <frac>a<den>3</frac> a^b ==> a<sup>b</sup> a_j ==> a<sub>b</sub> But most of TeX users see odd that a^b was expressed as <msup><mi>a</mi><mi>b</mi></msup> in mathML. >>>> Some weeks ago I received a draft of manuscript prepared by a >>>> mathematician and will probably be published in MSOR journal in >>>> brief.

Well, he is mathematicians working in an educative program with mathematics online. He is writing a serie of papers and discusses some problems with TeX-based mathematics explaining why colleagues would change the chip. I do not can cite here because was a personal comunication, he sent me drafts of their papers are being prepared for publication in a Journal of mathematics and computers. I cited here as example that not all mathematicians feel confortable with TeX/LaTeX which was -I thought- you was claiming at this list.

In fact I never used the word official in my messages; I always refered to forums of developers and personal communications. Also never Microsoft did an official position regarding his lack of interest in mathematics, but many folks are claiming the contrary as excuse on why MathML is not being popular. The w3c never did an official position regarding lack of interest in web application and some other user?s needs, however WHATWG has been formed because disapointment with w3c philosophy. No? Moreover, Opera and Mozilla did an official position regarding the WHATWG work: Implementations would be incremental reusing the working base of HTML + DOM + CSS technology. Therefore, I believe that both Opera and Mozilla Foundation officially are saying NO to support of MathML for HTML5. ========== Since any debate and technical specification would be unuseful without browsers support. I carefully encourage to both Opera and Mozilla browser people to take an official position regarding mathematics on the work of the WHATWG. Points: MathML is being rejected by many people. MathML contains a number of technical weakness. MathML is violating available standards on the web such as XML, HTML, CSS, and DOM and do not fit in general guidelines of web desing (e.g. device independence, accesibility) not in the main rules of WHATWG manifesto. Any implementation of MathML is based in duplication of available resources, doing the good implementations difficult or imposible, with difficult maintenance of redundant code, and needing of aditional implementations, i.e. usual DOM or CSS need to be implemented independently of level of support of MathML in your browser. Proposal from the editor of this specification needs of more work that has been named above, since he adds a new special parsing mode to mixed content is not MathML. HTML5 Math has received broad interest in this list, including people from certain web comunities and mathematicians. There is increasing interest to do math on the web in a cheap (without special editors, special fonts, special DTDs...) and powerful ways: for example we can encode (ds)^2, whereas other groups using MathML (Distler blog, HERMES project...) still are unable to encode that trivial math after 10 years and three or four attempts to mathematics from the w3c. ========== > I initially offered you several proposals, one cheap was implementation > of a math attribute like a complement to the HTML class attribute, but > you offers us either further changes to embrace a never-working > specification (and violating basic guidelines of this WHATWG), embracing > a markup is ignored or no change in HTML.
