The definition of the function SymbolicSum is given as
In[79]:= ?SymbolicSum
SymbolicSum[f, {i, imin, imax}] attempts to find the value of Sum[f, {i, imin,
imax} ] for symbolic imin,imax. SymbolicSum[f, {i, imax}] evaluates the sum
--------------------
of f with i running from 1 to imax.
Even though the rule "symbolic imin,imax" is broken in the second sentence, the WRI
has a point there.
