[Help-glpk] A MathProg question

Why is:

minimize err : sum{i in I} w[i];

acceptable, but:

minimize err : max{i in I} w[i];

is not?

I can get the desired result by following example cf12b.mod, but I'm puzzled 
why glpsol 4.47 emits an error.  From reading the manual, I'd expect that any 
of the  iterated operators would be linguistically interchangeable w/ sum.
