/**
* <p>Qualifies a bean, injection or producer field as a PicketLink resource.</p>
*
* <p>It is usually used to configure a specific behavior for the extensions points provided by PicketLink. You
* can use this annotation with types, field or methods. If used in a field or method this usually means
* you're producing or injecting a specific PicketLink enabled bean.</p>
*
* <p>As an example, when using PicketLink IDM backed by a JPA identity store, you must produce a <code>EntityManager</code>
* using this annotation.</p>
*
* <p>Another usage example is when providing a custom {@link org.picketlink.authentication.Authenticator}.</p>
