+To summarize: the "relay" directive:
+- explicitly bounds the database to a single database
+ holding the real naming context;
+- automatically instantiates the rewrite-remap overlay;
+- automatically configures the naming context massaging
+ if the optional "massage" keyword is added
+
+If the "relay" directive is not used, the rewrite-remap
+overlay must be explicitly instantiated and the massaging
+must be configured, either by using the "suffixmassage"
+directive, or by issuing more sophisticate rewrite
+instructions.
+
+AttributeType/objectClass mapping must be explicitly
+required.
+
+Note that the rewrite-remap overlay is not complete nor
+production- ready yet.
+Examples are given of all the suggested usages.
