 * If the {@link WithAnnotations} annotation is applied to a portable extension observer method, then only
 * {@link ProcessAnnotatedType} events for types which have at least one of the annotations specified are observed. The
 * annotation can appear on the annotated type, or on any member, or any parameter of any member of the annotated type, as defined 
 * in section <a href="http://docs.jboss.org/cdi/spec/1.2/cdi-spec.html#alternative_metadata_sources">11.4 Alternative metadata sources</a>. 
 * The annotation may be applied as a meta-annotation on any annotation considered.
