    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,

    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.
