Hi!
If you intend to develop a
SOAP web service that conforms with the WS-I Basic Profile 1.1, then operator overloading is not allowed. From the BP:
4.5.3 Distinctive Operations
Operation name overloading in a wsdl:portType is disallowed by the Profile.
R2304 A wsdl:portType in a DESCRIPTION MUST have operations with distinct values for their name attributes.
Note that this requirement applies only to the wsdl:operations within a given wsdl:portType. A wsdl:portType may have wsdl:operations with names that are the same as those found in other wsdl:portTypes.
Best wishes!
