	7	* ${ixf:avg(xpathExp1, xpathExp2)} calculates the average of the results obtained from evaluating "xpathExp1" and "xpathExp2".
1.6	8	* ${ixf:avg(xpathExp, "10")} the outcome will be the average of the value resulting from evaluating "xpathExp" and the number 10.
1.3	9	* ${ixf:avg("10","12","100")} the result will be 40,66, which is the sum of 10 and 12 and 100 dividing by 3.

1.2	24	* Numerical values can be also enclosed within //single quotes// : ${ixf:avg('10','12','100')} OR //mix single and double quotes//, like this: ${ixf:avg("10",'12','100')}.
	25	* The default display for the average includes two decimal places.
