Right, and this is explicitly stated in the WS-I Basic Profile 1.0:

    R2710   The operations in a wsdl:binding in a DESCRIPTION MUST result in
    wire signatures that are different from one another.

    The Profile defines the "wire signature" of an operation in a
    wsdl:binding to be the fully qualified name of the child element of the
    soap:Body of the SOAP input message it describes...In the case of
    rpc-literal binding, the operation name is used as a wrapper for the part
    accessors. In the document-literal case, since a wrapper with the operation
    name is not present, the message signatures must be correctly designed so
    that they meet this requirement.

I believe that's why Axis defines an <operation> element in the <service>
definition in server-config.wsdd:

  <operation name="processEmployees" qname="ns1:processEmployees"
       returnQName="ns1:processEmployeesReturn" returnType="xsd:int"
       soapAction="" xmlns:ns1="http://www.ltree.com/types"
       xmlns:xsd=" http://www.w3.org/2001/XMLSchema">
   <parameter qname="ns1:emps" type="ns1:Employee"/>
  </operation>

The <operation> defines a mapping between the child element of the SOAP Body in
the request ("qname" attribute) to the method in the implementation class
("name" attribute). If the operation follows the wrapper-style convention, Axis
doesn't need the <operation> definition.
