Hello,

I would like to manually create some HTML which would be displayed
nicely in both HTML and PDF (using MKIV for conversion from HTML). To
a certain degree I'm able to fake mathematics with

<span class="math"><span class="letter">ax</span><sup>2</sup> + <span
class="letter">bx</span> + <span class="letter">c</span> = 0</span>

where <span class="math"> signals TeX to use \mathematics{...} and
<span class="letter"> signals web browser that the letter has to be
displayed in italic (I could use class="math", but this would also
make numbers italic).

But this is very cumbersome to write. MathJax offers an excellent way
to enter math formulas in an easy way (see attached HTML), but I'm not
sure how I could convince the XML parser to treat contents literally.
Any ideas?

Thank you very much,
    Mojca
