Thanks Nick, Robert! OK, then we settle on (2) for integral.

The remaining issue is now to settle the conventions for derivative.
Currently, maxima uses "\\partial"  symbol even for functions
of single variable.  I think it would be better if we follow the
arguments of
http://trac.sagemath.org/sage_trac/ticket/4202
for derivative of function with single variable.  So here are the situations

(1)  diff( f(x), x)   =>
--------------------
 (a)  Current scheme via Maxima:
       {{{\it \partial}}\over{{\it \partial}\,x}}\,f\left(x\right)

 (b) Proposed:
       \frac{d f\left(x\right)}{d x}


(2)  diff( f(x, y), x)   =>
--------------------
 (a)  Current scheme via Maxima:
       {{{\it \partial}}\over{{\it \partial}\,x}}\,f\left(x, y\right)

 (b) Proposed:
       \frac{\partial f\left(x, y\right)}{\partial x}

We follow similar scheme for higher derivatives.

Once this convention is settled, I will be ready to submit
the final patch including doc-tests.

Cheers,
Golam
