Except that Microsoft Windows does not work for those tasks better done with several Unix, Linux, real-time OS...

Enough examples on why MathML code is being spreaded on the web is often poor than old alternatives was extensively discussed at this list.

Again weak semi-defined arguments. What exactly would I understand by your "it *IS* the standard"? I suspect that you mean theoretical advantages from using all of us an unified language for the interchange of information and posible benefits from existence of an unified collection ot tools, but wait your confirmation. Any case ISO-12083 *IS* an previous international standard (MathML is technically a w3c recommendation not a standard because w3c is not a standards body) and I do not see you promiting its usage, why?

Well, in that case MathML and OpenMath are not penetrating much. Yes there is some usage of MathML off-line at the publishers side, but usage of MathML online is minimal. > Success of a product doesn't mean that I like it particularly well, that I > don't think it could or should be improved, or that there are no > conceivable alternatives that would better serve my purposes.

People using (and satisfied with) MathML can continue using whereas alternatives are proposed and developed for others. In fact this thread is titled "Math on the web without MathML (CSS 2.1 rendering for HTML and XML)"... People enthusiastic with presentational MathML can continue using MathML, IteX, plugins, and all the rest. Others can take a different way. A thing irritating me is the only-way concept you (and others) are trying to promote without real rationale for leaving alternatives. How expressed many times here if MathML is so good and so popular and so succesfull, nobody would become interested in alternatives, therefore you would not worry about my writtings after all. >>> What do you mean by "content" and "meaning" such that content MathML is >>> about the one but not about the other?

Maybe but reply was addresed to you. You claims MathML is succesfull in "market terms" and you are promoting it without solid technical basis. You also find CSS rendering of no interest and even initially claimed that rendering of math would be addressed in another part (even claimed that math on the web posts would be submitted outside this list!). You also claim that you are using MathML because is the "standard". MathML is about communication (including rendering) and storing of mathematics. If you prepare a document using c-MathML for above examples (ups! you erased them from your reply) and I want receive the document and proccess it with a MathML aware software, I would know _what_ you will send me before I begin to write the code for the software, right? After all one of advantages of using a "standard" is many people can write and interchange code in a unified way, no? How is possible that you can maintain that MathML is working and is succesfull in function of "objective data" but cannot even encode something so simple as (a+b) in content or parallel MathML. Are your claims about success and working so political and marketing based as youir thoughts about Windows or Beta or there is real stuff beyond your thoughts? I know claims from other people (including MathML folks); i agree with some and disagree with others but you sound more as waporware to me. ### It is time also for a MathML 3 spec, I have proposed some basic ideas for the new spec (I do not know if will be accepted or rejected). You often claim how good MathML would be if you had done! If I remember correctly Patrick encouraged you to post here some ideas for MathML 3 discussion but your messages continue lacking technical stuff in an alarming way. <note> The "experiment" about content MathML and the encoding of the examples was addressed to Mark P. Line but will be followed by another technical _suggestion_ for the MathML WG. </note> > If you have > examples that cannot be encoded correctly in content MathML by anybody > because the language is inadequate, then I'm certainly not the person you > need to talk to.

I already said about problems of designing a content oriented markup without special emphasis on rendering issues. Problems and other trouble were recognized at the STM workshop on scientific languages, by Fateman in his criticism of OpenMath... There are also lessons from the SGML world to be learned here. <blockquote> Historically, it's a common mistake to develop markup systems without giving much thought to presentation. For example, only when SGML was done did one start efforts to create a style sheet language for it (FOSI/DSSSL). </blockquote> > >> It is not how you think that one can design a content markup for people >> who is not interested in rendering issues and next one design a >> presentational layer for rendering. > > How do you know?
