Looking at RecSourceListNode which also has add() method which adds the
argument into both items and dsqlChildNodes, I see such usage:
querySpec->dsqlFrom = FB_NEW_POOL(getPool())
RecSourceListNode(getPool(), 1);
querySpec->dsqlFrom->items[0] = dt;
so the argument is added only to items but not to dsqlChildNodes. There
are many such cases, actually. Don't they defeat the "default
processing" idea? It looks suspicious at the first glance.
