The m:Add method name element in line 6 contains the name of the method (Add) we wish to call, and the namespace it is found in (uri:my-calculator). The URI (Universal Resource Indicator) specifies which computer offers an Add method web service.

Lines 7-8 define two arguments (Parameter1 and Parameter2) that the Add method requires. In this example, the numbers to be added are 2 and 3.

Line 9 closes the method name element.
