There is linear format used by Microsoft Office and described in
http://unicode.org/notes/tn28/ by Murray Sargent. It is very close to
natural representation of math formulas and what you describe. But it
still does not declare any rendering rules, only semantics.
Thanks,

Subject: Root and fraction (2 new symbols)
Good day.
Impossibility to write commonly used formulas with root and fraction
_in textual_ file looks poorly, archaically too.
But symbols 'root' and 'fraction' exist! Why nobody guess to interprete
them as control symbol.
Let's agree to display expression "(a+b+c)\(d+e)" as
a+b+c
-----
d+e
and expression "a#(b+c)" (where # is mark of root) as
a ___
\/b+c
P.S.
At least, it's possible to add two new symbols with mentioned
funtionality.
