Comment: I notice that going this way in Firefox 2.0.0.1 for Linux
(public build of 20061208) corrects the fallen primes problem for
example 22 of the "Torture Test" (in mtext at math-depth 7).
On the other hand it seems to have no effect on the fallen display for
the ascii values 0x22 and 0x27 at
http://www.mozilla.org/projects/mathml/fonts/chars/table00xx.html.
The latter is probably a font issue since my casual glance at the
javascript indicates that no MathML, e.g., mtext in math, is involved.

Question: For linux what is the advantage of the present default
font spec (in mathml.css) over the simpler value CMSY10, CMEX10?

Comment: I've pretty much come to the conclusion that unicode values
should be displayed in math as much as possible like they are normally
displayed in ordinary HTML and that empty elements <prime/> and
<backprime/> [these would be SDATA if that were available] should be
introduced to parallel the behavior of \prime and \backprime in LaTeX
with amsmath.  (Alternatively one could use special attribute values
when &prime; or &backprime; are isolated instances of cdata, but that
would not, for example, cover their use in mtext.)
