Well, i revised a bit is being done here. I find the zip with the
documentation with the next MathML example:

<m:math id="math001" smilref="example1.smil#math001"
altimg="example1-001.png" alttext="f of x">
    <m:mi> f </m:mi>
    <m:mo> &ApplyFunction; </m:mo>
      <m:mo> ( </m:mo>
      <m:mi> x </m:mi>
      <m:mo> ) </m:mo>

Great, a simple f(x) is being accesible not because using some
ultra-advanced conception but just an simple Unicode entity: 
&ApplyFunction; Entity can be used in any other markup and approach
supporting Unicode.

As said in a previous communication i revised many sites using MathML and
the accesibility of the code was always poor than using the old GIF+ALT
approach. I see amazing that the group is attempting to add accesibility
using presentational markup!

Yes, there is a few more (UNICODE) entities: &InvisibleTimes;
&InvisibleComma; &DifferentialD; &ExponentialE; &ImaginaryI; but
difficulties with they obligate to some MathML folk to recomend avoiding
usage in cases where visual rendering is ugly.

Well, an accesible encoding of f(x) appears to be solved with above MathML
code, now the DAISY project would go a bit longer and try to provide us a
more difficult example, for instance f(x) = x^2

it would be amazing to see the "accesibility" of
