    Just spoke with Core leadership about this. The use of separate status
    variables seems to be the new direction, rather than the use of arrays
    of status enums. There are several new status variables being added
    (proposed, anyway) to EnabledLogicalElement in a new CR. I think this
    is a reasonable directon for us to take. If someone has a better
    partitioning of the items than this traditional one, please elaborate.

    Ira, regarding our discussion on SubUnitStatus today, I think that there
    are (at least) two choices: either a vector of enum values or several
    separate variables. It might not be thoroughly unreasonable to break it
    into five variables representing the five sections that were or-ed
    together in the first place.

    StatusAvailability enum
            0 idle
            1 on request, unavailable
            2 standby
            3 broken, unavailable
            4 active
            5 unknown
            6 busy
    StatusCriticalAlert Boolean
    StatusNonCriticalAlert Boolean
    StatusOnline Boolean
    StatusTransitioning Boolean

    It's an idea, anyway. Whaddyathink?

    For comparison, here is the section from the MIB intro, from which I
    cribbed the text above.

       The PrtSubUnitStatusTC is an integer that is the sum of 5 distinct
       values, Availability, Non-Critical, Critical, On-line, and
       Transitioning. These values are:

       Availability value

               Available and Idle 0 000'b
               Available and Standby 2 010'b
               Available and Active 4 100'b
               Available and Busy 6 110'b
               Unavailable and OnRequest 1 001'b
               Unavailable because Broken 3 011'b
               Unknown 5 101'b

       Non-Critical

               No Non-Critical Alerts 0
               Non-Critical Alerts 8

       Critical

               No Critical Alerts 0
               Critical Alerts 16

       On-Line

               State is On-Line 0
               State is Off-Line 32

       Transitioning

               At intended state 0
               Transitioning to intended state 64
