Here are a couple more samples. I'll go slowly because
I know there are adjustments to be made. Comments are
very helpful.

---------------------------------------------------------
Item 5 / pre-superscript
TeX: {}^tx
Wolfram: x^^^t
MINSE: 'fct(x,t)
Display-List (S): <mprescripts>x<mc><mc>t</mscripts>
Display-List (MS):
ISO 12083: x<sup location="pre">1</sup>
Notes:
1. I believe MINSE has no 'primitive' pre-scripting facilities (analogous
to ";"). The function of the pre-scripting operator has to be encoded
within a compound (arbitrarily named "fct" here).
---------------------------------------------------------
Item 6 / superscript and pre-superscript
TeX: {}^tx^2
Wolfram: x^^^t^2
MINSE: 'exp('fct(x,t),2) or 'fct(x,t)^2
Display-List (S): <mscripts><mprescripts>x<mc><mc>t</mscripts><mc><mc>2</mscripts>
Display-List (MS):
ISO 12083: x<sup location="pre">1</sup><sup>2</sup>
Notes:
1. Is it true that DisplayList format has no "flat" rendering for
this? i.e. the expression is nested one way or another (in
expression, not rendering)? Not a 'problem', just wondering.
2. In cases where tensor notation is *not* required, I assume that
strings of characters can also be used in Wolfram notation, a la
"x^^^{t_1}^2" and "x^^^{ut}___1^2".
