    At today's WIMS-CIM WG telecon, we discussed a problem
    Walt Filbrich (Samsung) found during his prototyping of
    the Imaging System State and Counter MIB (aka Counter
    MIB v2).

    Background: As Walt observed, the intent of the Abstract
    Counter Spec (PWG 5106.1) and its SNMP binding in the
    Counter MIB is to be able to expose _all_ of the usage
    counters that MFDs currently report through proprietary
    interfaces (particularly embedded web servers).

    Eventually, there will probably be a PWG Scanner MIB
    but, for now, there is no way to distinguish the specific
    type of scanner subunit (i.e., ADF versus Platen) for
    counts. But many MFDs separately record and report the
    counts for ADF versus Platen.

    The proposed solution is to add two values to the
    icSubunitTypeTC textual convention, in addition to
    the existing generic value 'scanner(50)':

      scannerADF(503) -- scanner with automatic document feeder
      scannerPlaten(504) -- scanner with manual platen

    The unanimous concensus at today's WIMS-CIM WG telecon
    was that this was a good idea. We'd like wider review,
    before adding this to a Counter MIB working draft.

    Please send your comments quickly.
