 ### Generic Procedure
 
-The procedure to autoload constant `C` in an arbitrary situation is:
+Relative references are reported to be missing in the cref where they were hit,
+and qualified references are reported to be missing in their parent. (See
+[Resolution Algorithm for Relative
+Constants](#resolution-algorithm-for-relative-constants) at the beginning of
+this guide for the definition of *cref*, and [Resolution Algorithm for Qualified
+Constants](#resolution-algorithm-for-qualified-constants) for the definition of

-# For relative references C is missing in the cref, and for qualified

+The procedure to autoload constant `C` in an arbitrary situation is as follows:
