3. Past Usage: unknown

4. Relevant Information:
   -- Explanation: I suspect this was left by Ross Quinlan in 1987 at the
      4th Machine Learning Workshop.  I'd have to check with Jeff Schlimmer
      to double check this.

   -- The '-' values are actually 'not_applicable' values rather than
      'missing_values' (and so can be treated as legal discrete
      values rather than as showing the absence of a discrete value).
