+    //  Summary:
+    //  A semantic action policy that insert data into an associative
+    //  container using a const reference to data.
+    //  (This doc uses convention available in actors.hpp)
+    //
+    //  Actions (what it does):
+    //      ref.insert( T::value_type(value,value_ref) );
+    //      ref.insert( T::value_type(T::key_type(first,last), value_ref));;
+    //
+    //  Policy name:
+    //      insert_key_action
+    //
+    //  Policy holder, corresponding helper method:
+    //      ref_const_ref_value_actor, insert_key_a( ref, value_ref );
+    //
+    //  () operators: both
+    //
+    //  See also ref_const_ref_value_actor for more details.
