It would be boring repeating again and again and again. I can cite again
(one of my July messages) some quotes from a recent workshop on MathML for

The utility of MathML to enhance searching and improve accessibility of
online mathematical content has not yet been proven.

Searching of mathematically laden content by the mathematics it contains
is a complex issue. It's not altogether clear whether the level of
description implicit in content (semantic) and/or presentational MathML is
sufficient to support robust searching on the mathematics contained in a

It's also not yet certain that readers and other accessibility tools will
be able to exploit MathML effectively to make the mathematics embedded in
a resource more accessible, though that seems a safer bet.

While MathML is being adopted (at least experimentally) behind the scenes
-- e.g., as an exchange format for interoperation between applications
like Mathematica and Maple and in the editorial workflow of scholarly
journals, it has not been widely adopted by the authors of educational and
scholarly mathematical content.

Of course, you can disagree and then add lot of fields were MathML is
successful for you. That would be great for all of us here. Maybe we would
first begin to analize that “sucesfull” mean.

Maybe I would remember you that MathML is about communicating something:
mathematics. Presentation MathML is about visual rendering, whereas
content MathML would be about transfer of precise mathematical content
(not meaning). Ok, let us focus then on that: communication. I am just
curious how you (or your software) would encode next basic expressions

1) a + b

2) sin &pi;

3) -5

4) &int; sin &omega; d&omega;

5) 3/4

6) sqrt(x)/(y^2 -1)

7) -x

8) &int;_a^b &omega; d&omega;

9) x >> 0

10) <p>My favourite Greek letter is &beta;</p>

11) x_i = 5

12) {}^7log x

13) (x+3)^2

14) a/b; a=3, b=4

15) 123/456

16) (&partial;&rho; / &partial;t) = L &rho; + &epsilon;(&rho - &rho;_0)

in content (or parallel) MathML and how would I (or my software) interpret

Of course, this is more than a theoretical exercise; take as practical
exercise the internal and or external communication of research results at
some official body.

Why not? In fact, without rendering how can you read my message here? The
100% of math books in the University’s library are rendering math on
