/**
* AddressingFeature represents the use of WS-Addressing with either
* the SOAP 1.1/HTTP or SOAP 1.2/HTTP binding. Using this feature
* with any other binding is undefined.
* <p>
* This feature can be used during the creation of SEI proxy, and
* {@link Dispatch} instances on the client side and {@link Endpoint}
* instances on the server side. This feature cannot be used for {@link Service}
* instance creation on the client side.
* <p>
* The following describes the effects of this feature with respect
* to be enabled or disabled:
* <ul>
* <li> ENABLED: In this Mode, WS-Addressing will be enabled. It means
* the endpoint supports WS-Addressing but does not require its use.
* A sender could send messages with WS-Addressing headers or without
* WS-Addressing headers. But a receiver MUST consume both types of
* messages.
* <li> DISABLED: In this Mode, WS-Addressing will be disabled.
* At runtime, WS-Addressing headers MUST NOT be used by a sender or
* receiver.
* </ul>
* <p>
* If the feature is enabled, the <code>required</code> property determines
* whether the endpoint requires WS-Addressing. If it is set true,
* WS-Addressing headers MUST be present on incoming and outgoing messages.
* By default the <code>required</code> property is <code>false</code>.
*
* <p>
* If the web service developer has not explicitly enabled this feature,
* WSDL's wsam:Addressing policy assertion is used to find
* the use of WS-Addressing. By using the feature explicitly, an application
* overrides WSDL's indication of the use of WS-Addressing. In some cases,
* this is really required. For example, if an application has implemented
* WS-Addressing itself, it can use this feature to disable addressing. That
* means a JAX-WS implementation doesn't consume or produce WS-Addressing
* headers.
*
* <p>
* If addressing is enabled, a corresponding wsam:Addressing policy assertion
* must be generated in the WSDL as per
* <a href="http://www.w3.org/TR/ws-addr-metadata/#wspolicyassertions">
* 3.1 WS-Policy Assertions</a>
*
* <p>
* <b>Example 1: </b>Possible Policy Assertion in the generated WSDL for
* <code>&#64;Addressing</code>
* <pre>
* &lt;wsam:Addressing wsp:Optional="true">
* &lt;wsp:Policy/>
* &lt;/wsam:Addressing>
* </pre>
*
* <p>
* <b>Example 2: </b>Possible Policy Assertion in the generated WSDL for
* <code>&#64;Addressing(required=true)</code>
* <pre>
* &lt;wsam:Addressing>
* &lt;wsp:Policy/>
* &lt;/wsam:Addressing>
* </pre>
*
* <p>
* <b>Example 3: </b>Possible Policy Assertion in the generated WSDL for
* <code>&#64;Addressing(required=true, responses=Responses.ANONYMOUS)</code>
* <pre>
* &lt;wsam:Addressing>
* &lt;wsp:Policy>
* &lt;wsam:AnonymousResponses/>
* &lt;/wsp:Policy>
* &lt;/wsam:Addressing>
* </pre>
