		3	The sum function is used to perform the addition of two or more values, which could be either numerical values or xpath expressions.
		4
		5	== Syntax : ==
		6
		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.
		10
		11	Ensure that numerical values are between double quotes : ${ixf:sum("10","12","100")},
		12
		13	while xpath expressions should remain without any quote enclosures.
		14
		15
		16	== Example : ==
		17
		18	* ${ixf:sum(Documents/Order/DeliveryAddress/OrderLine/Price,"10"}
		19
		20	Let's suppose that the result of //Documents/Order/DeliveryAddress/OrderLine/Price// is 30, so the sum is 40.
		21
		22	== Note: ==
		23
		24	Numerical values can be also enclosed within single quotes : ${ixf:sum('10','12','100')} OR mix single and double quotes, like this: ${ixf:sum("10",'12','100')}.
