* Java 5 Annotation <code>Attributes</code> metadata implementation used for secure method interception.<p>This
* <code>Attributes</code> implementation will return security configuration for classes described using the
* <code>Secured</code> Java 5 annotation.</p>
* <p>The <code>SecurityAnnotationAttributes</code> implementation can be used to configure a
* <code>MethodDefinitionAttributes</code> and <code>MethodSecurityInterceptor</code> bean definition (see below).</p>
* <p>For example:<pre>&lt;bean id="attributes"
* class="org.springframework.security.annotation.SecurityAnnotationAttributes"/>&lt;bean id="objectDefinitionSource"
* class="org.springframework.security.intercept.method.MethodDefinitionAttributes"> &lt;property name="attributes">
* &lt;ref local="attributes"/> &lt;/property>&lt;/bean>&lt;bean id="securityInterceptor"
* class="org.springframework.security.intercept.method.aopalliance.MethodSecurityInterceptor"> . . .
* &lt;property name="objectDefinitionSource"> &lt;ref local="objectDefinitionSource"/> &lt;/property>
* &lt;/bean></pre></p>
* <p>These security annotations are similiar to the Commons Attributes approach, however they are using Java 5
* language-level metadata support.</p>
* <p>This class should be used with Spring 2.0 or above, as it relies upon utility classes in Spring 2.0 for
* correct introspection of annotations on bridge methods.</p>
