Re: MathML Core authoring tools?

It is a good idea to have a LaTeX file that tests MathML core.
It will also serve as a quick way for people to see how to
author various constructions.

Are there ideas for how the LaTeX source will be aware that
|A|
means absolute value (or whichever of the many other
things it might mean)?

I think it is reasonable to have several macros

\abs{A}
\det{A}
\card{A}

all of which render as
|A| .
But where is the information which provides the intent?
