Really?  RFC-1771, sec 9, par 5 sez:

   If the UPDATE message contains a feasible route, it shall be placed
   in the appropriate Adj-RIB-In...                    ^^^^^
                                                       |||||

And sec 3.2, par 5 sez:

   In summary, the Adj-RIBs-In contain unprocessed routing information
                                       ^^^^^^^^^^^
   that has been advertised to the local BGP speaker by its peers;
