There are (at least) three artifacts involved:

 a) The text that should be pronounced by a screen reader ( the alt
    text in <img
   alt= "E(aX+b)=aE(X)+b" /> )

 b) The underlying semantic representation, possibly MathML,
   possibly TeX). As (a) shows you can sometimes _say_ TeX (and
   sometimes arguably not: \Large f(x)=\int_{-\infty}^x e^{-t^2}dt), but
   nobody should ever be forced to listen to MathML spoken aloud
   because it looks like this: "...<mrow><msup><mfenced open=
   "[" close="]"><mrow><mi>a</mi><mo>+</mo>..."

 c) The <img> that is the rendering of the underlying semantic

But the Wikipedia work is certainly a good start at an examples list,
and in my Googling around I came across several others. Although I
have a sneaking suspicion this might not really be a big-M uf thing,
it's certainly seems worth gathering more examples as ammunition
for whatever next step is appropriate.

In that case, you're going to _hate_ microformats, because they
don't so much escape those kinds of hacks as enshrine them
as standards :-)
