RE: Rationale to close the operation overloading issue

The approach works for methods with any number of arguments since you can
define corresponding XML Schema types. In your example,

getAddress(socialNo)
getAddress(name, surname)
getAddress(login)

I'd use the following type:

    <complexType name="getAddressType">
        <choice>
            <element name="socialNo" type="string"></element>
            <element name="nameSurname">
                <complexType>
                    <sequence>
                        <element name="name" type="string"></element>
                        <element name="surname" type="string"></element>
                    </sequence>
                </complexType>
            </element>
            <element name="login" type="string">
            </element>
        </choice>
    </complexType>

There are many other equivalent ways to represent the method signatures as
XML Schema.

But this works only, if you have the same number of parameters.
