Well, according to the Admin Guide:

 "For directories, the client can specify a management
  class by using the DIRMC option in the client options file.
  If no management class is specified for a directory,
  ADSM chooses the management class with the longest
  retention period in the backup copy group (retention
  period for the only backup version)."

Of course, this makes perfect sense, because ADSM wants to keep
directories around for at least as long as the files those
directories contain are kept.
