/**
 * A ServiceDescription corresponds to a Service under which there can be a collection of enpdoints.
 * In WSDL 1.1 terms, then, a ServiceDescription corresponds to a wsdl:Service under which there are
 * one or more wsdl:Port entries. The ServiceDescription is the root of the metdata abstraction
 * Description hierachy.
 * 

* The Description hierachy is: *

 * ServiceDescription
 *     EndpointDescription[]
 *         EndpointInterfaceDescription
 *             OperationDescription[]
 *                 ParameterDescription[]
 *                 FaultDescription[]
 * 

* ServiceDescription details *

* CORRESPONDS TO: * On the Client: The JAX-WS Service class or generated subclass. *

* On the Server: The Service implementation. Note that there is a 1..1 * correspondence between a ServiceDescription and EndpointDescription * on the server side. *

* AXIS2 DELEGATE: None *

* CHILDREN: 1..n EndpointDescription *

* ANNOTATIONS: * None *

* WSDL ELEMENTS: * service *
