        binding.setAnnotationType(type);
        binding.setPredicate(alwaysTrue());
        binding.setFactory(new StereotypeVisitorFactory(annotationType));

        binding.setFactory(new GenericVisitorFactory(element.getName(), element.getNameSpace()));
        bindings.add(binding);

    // Its IMPORTANT that the @Ignore is processed last since it removes existing bindings
    if (ignoredDiscovery.isIgnore()) {
        m_reporter.trace("@Ignore detected: @%s", type.getClassName());
        Binding binding = new NullBinding(type);
        bindings.clear();

}
