| A tag interface implemented by a BeanLocator indicating that it
puts itself forward as a "fallback" resolver of bean requests. If
a bean definition is not found in the main request container, all
bean of type "FallbackBeanLocator" will be queried in turn for a bean
of the required name. Their behaviour for a not found bean will be to
return null rather than throw a BeanDefinitionNotFound exception.
The first FallbackBeanLocator that returns an object will terminate the
search. Otherwise, location will continue in the parent locator.
NB - this mechanism will probably be replaced once we support "proper"
Spring parent containers.
