+/**
+ * This annotation can be applied to a package, class or method to indicate that
+ * the method parameters in that element are nullable by default unless there is:
+ * <ul>
+ * <li>An explicit nullness annotation
+ * <li>The method overrides a method in a superclass (in which case the
+ * annotation of the corresponding parameter in the superclass applies)
+ * <li> there is a default parameter annotation applied to a more tightly nested
+ * element.
+ * </ul>
+ * <p>This annotation implies the same "nullness" as no annotation. However, it is different
+ * than having no annotation, as it is inherited and it can override a ParametersAreNonnullByDefault
+ * annotation at an outer scope.
