   -- Generated Names --
   ---------------------

   --  This section lists the various cases of generated names which are
   --  built from existing names by adding unique leading and/or trailing
   --  upper case letters. In some cases these names are built recursively,
   --  in particular names built from types may be built from types which
   --  themselves have generated names. In this list, xxx represents an
   --  existing name to which identifying letters are prepended or appended,
   --  and a trailing n represents a serial number in an external name that
   --  has some semantic significance (e.g. the n'th index type of an array).
