RPC-Style Web Services

The RPC-style invocation is the most common.
The method call is represented as a single structure with each in or in-out parameter modeled as a field in that structure.
The names and physical order of the parameters must correspond to those in the method.

For example, the Java method

	    String check(String paramA, String paramB);

will use the SOAP envelope

<s:Envelope xmlns:s="...">
  <s:Body>
    <check xmlns=".."
        s:encodingStyle="http://www.w3.org/2001/06/soap-encoding">
      <paramA xsi:type="string">abs123</paramA>
      <paramB xsi:type="string">
      Bob's store
      </paramB>
    </check>
  </s:Body>
</s:Envelope>
