  // opaque values that are assigned to each modification to the
  // repository's state. An incarnation number can be quoted when
  // invoking the list_types operation to retrieve all changes to the
  // service repository since a particular logical time. (Note:
  // IncarnationNumber is currently declared as a struct consisting of
  // two unsigned longs; what we really want here is an unsigned hyper
  // [64-bit integer]. A future revision task force should modify this
  // when CORBA systems support IDL 64-bit integers.)

  // If the "name" parameter is malformed, then the
  // CosTrading::IllegalServiceType exception is raised.  If the type
  // already exists, then the ServiceTypeExists exception is raised.
