The thing Jim Dunleavy is talking about is LaTeX, a text-based language used
by LOTS of people in math and science to generate equations and to do other
kinds of formatting / typesetting.
Just guessing, the way Alt text would work is for the Alt text / label to be
the actual LaTeX code that produces the different figures. A reader needs to
understand the LaTeX code in order to parse out what symbols are involved,
but typically someone working in the field might know that anyway from
writing the code to produce their own equations. The sighted user just sees
whatever figure is created by the LaTeX code and is indifferent to the code.
As for whether or not everything on Wikipedia follows a given convention, I
assume that is greatly to be hoped for but not guaranteed, just due to the
nature of Wikipedia.
Probably I could do some actual testing/ research to verify these points,
but perhaps this is enough to help you get started.
