 /**
  * Strategy for creating {@link BeanInfo} instances.
  *
+ * <p>BeanInfoFactories are are instantiated by the {@link CachedIntrospectionResults},
+ * which looks for {@code META-INF/spring.beanInfoFactories} files on the class path.
+ * These files contain one or more {@code BeanInfoFactory} class names, each of a single
+ * line. When a {@link BeanInfo} is to be created, the {@code CachedIntrospectionResults}
+ * will iterate through the discovered factories, asking each one if it {@linkplain
+ * #supports(Class) supports} the given bean class. If it does, {@link
+ * #getBeanInfo(Class)} will be called; if not, the next factory will be queried. If none
+ * of the factories support the class, an standard {@link BeanInfo} is created as a
+ * default.
+ *
+ * <p>Note that the {@link CachedIntrospectionResults} sorts the {@code BeanInfoFactory}
+ * instances by {@link org.springframework.core.annotation.Order Order}, so that ones with
+ * a higher precedence come first.
