+
+// = DESCRIPTION
+//   Interface code generation is complex, the client stubs require
+//   two different class and the server also require other two.
+//   Only one of them includes whatever nested typedefs, exceptions
+//   and or structures are defined in the interface.
+//   To break this complexity a different visitor is used for each
+//   case.
+//
+// = NOTE
+//   Visitors were added recently into the compiler, so some
+//   code is still generated using the old "state oriented" approach;
+//   notably only the _collocated class is actually generated using
+//   the visitor, in the other cases (the interface class and the
+//   skeleton class) we still call back the old code generation
+//   methods.
