/**
 * Holder for a BeanDefinition with name and aliases.
 *
 * <p>Recognized by AbstractAutowireCapableBeanFactory for inner
 * bean definitions. Registered by DefaultXmlBeanDefinitionParser,
 * which also uses it as general holder for a parsed bean definition.
 *
 * <p>Can also be used for programmatic registration of inner bean
 * definitions. If you don't care about BeanNameAware and the like,
 * registering RootBeanDefinition or ChildBeanDefinition is good enough.
