My assessment would be that this provides wider accessibility e.g. for
sighted users and general clarity and usability including ease of use for
authors and for screenreader users it would be easy to include or link to
the kind of description you would put as alt text if the Mathjax
functionality doesn't provide the equivalent of that.

What would be considered more accessible:

.        this using fonts which do scale but don't have alt text or

.        an image with alt text="x equals negative b plus or minus square
root of etc, etc"  which can be read out?

Just curious.

Well, I'm sure Alistair would agree that it would be better to do something
that is of limited accessibility to some, but of great use to many, rather
than do nothing, with no benefit to anyone. But he would encourage us to
find ways to make it accessible if it were possible.

Well, it should be a lot more accessible then the previous solution, as it
is displayed using fonts in stead of generating an image. So you can also
zoom in, etc.

But I don't know what a screen reader makes of this.

It the moment it uses a link to a website maintained by MathJax. It is not
pure Javascript. There is a whole engine behind it apparently. You can
install it locally (the installer is 16.7 Mb).

Cool - how accessible is it?

Why doesn't it work off line?

Like I tried to explain in a different e-mail...

- Based on MathJax (http://www.mathjax.org, as found by Pat)
- Only works in Javascript/HTML5
- Doesn't interfere with previous solution
- Like previous solution, doesn't work off-line
