One thing I am stuck on: in principle it is possible to format these sum expressions into exactly the original notation used in the question. For instance, Format[sum[x^p_]] := \!\( \*UnderoverscriptBox[\(\[Sum]\), \(i = 1\), \(n\)] \*SuperscriptBox[ SubscriptBox[\(x\), \(i\)], \(p\)]\) handles simple cases like sum[x^3]. But how to extend this to the general case? (Among other things, we need a way to introduce different bound variable names such as "i" and "r", or perhaps $i_1, i_2, $ etc.)
