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.

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.

Now I understand the confusion. I thought that was clear that I was using

Maybe we would use content MathML 2.0 and prefix notation for efficient

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.

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,

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.
