Re: New writeup for intent examples

I figured I should read more carefully what you wrote in
https://mathml-refresh.github.io/mathml/docs/intent.html even though you
hadn't done an update yet. In case you didn't fix it, the MathML for
"Binomial as stacked numbers" is not right. Probably you want it to be an
mfrac, but an mtable could also be used. Kind of garbled in the version I
read.

I still don't like the way you handle plus/minus, but that's not really a
criticism of the intent idea...

I don't think the "Differential alone in the numerator" is correct. The
'intent' on the mfrac should block the higher level intent from seeing the
'x' inside it. Further, the 'x' should not be in an <mtext>. Same issues
for the next differential examples.
