7		-* ${ixf:sum(xpathExp1, xpathExp2)} calculates the sum of the results obtained from evaluating "xpathExp1" and "xpathExp2".
8		-* ${ixf:sum(xpathExp,"10")} the result will be the sum of the result obtained from evaluating "xpathExp" and 10.
9		-* ${ixf:sum("10","12","100")}  the result will be 122, which is the sum of the individual results of "10", "12", and "100".
