  However, at a Python level, nodes are accessed as attributes (or
  members), so the right exception should be AttributeError.  If we want
  to give this kind of access an additional meaning in PyTables, then
  maybe a new subclass of AttributeError (e.g NodeError) should be
  defined and used instead.  In addition, this would not break
  compatibility with existing code where AttributeError was caught.
  Well, this is just an alternative.  Bye!
