/**
* The "Wrapper Style" WSDL operation is defined by The Java API for XML-Based
* Web Services (JAX-WS) 2.0 specification, section 2.3.1.2 Wrapper Style. <p/>
* A WSDL operation qualifies for wrapper style mapping only if the following
* criteria are met:
* <ul>
* <li>(i) The operations input and output messages (if present) each contain
* only a single part
* <li>(ii) The input message part refers to a global element declaration whose
* localname is equal to the operation name
* <li>(iii) The output message part refers to a global element declaration
* <li>(iv) The elements referred to by the input and output message parts
* (henceforth referred to as wrapper elements) are both complex types defined
* using the xsd:sequence compositor
* <li>(v) The wrapper elements only contain child elements, they must not
* contain other structures such as wildcards (element or attribute),
* xsd:choice, substitution groups (element references are not permitted) or
* attributes; furthermore, they must not be nillable.
* </ul>
