org.apache.axis2.jaxws.description.ParameterDescription
A ParameterDescripton corresponds to parameter to a method on an SEI. That SEI could be explicit (i.e. WebService.endpointInterface=sei.class) or implicit (i.e. public methods on the service implementation are the contract and thus the implicit SEI).
ParameterDescriptons contain information that is only relevent for and SEI-based service, i.e. one that is invoked via specific methods. This class does not exist for Provider-based services (i.e. those that specify WebServiceProvider)
```
