Hi Pete,                                        Wednesday (15 July 2009)

Here are my comments on 10 July SM/2.0 schema:

(1) I like the generalization of Printer[Status/Description] elements
    reflected in PwgDeprecated.xsd
    - I agree with Bill that there may yet be more to generalize
    - Note this boils down to applying IPP to MFD services - Good Thing

(2) I like the rework of System

(3) I like the rework of NaturalLanguage and Charset
    - IETF just approved RFC 4646bis, so a new RFC reference this fall

(4) In SubunitStates please capitalize (for consistency):
    coverOpen/Closed, interlockOpen/Closed, and other

(5) In SubunitStatus type definition and numerous other places in schema
    - SPY has jumbled XML comments randomly out-of-line

(6) StorageDataEncryption should be StorageDataEncryptionIsEnabled,
    since it's a boolean not an enum (w/ default to false)
    - see lines 59 to 65 in Subunits.xsd

(7) MediaPathStatus should include SheetsCompleted like
    ScanMediaPathStatus (though the property's not in Printer MIB)
    - What are the semantics?
    - Are these Lifetime or PowerOn counters?

(8) FinisherSupply (from Finisher MIB) and
    MarkerSupply (from Printer MIB) should probably be combined into
    - in recent MIB walks, many manufacturers list FinisherSupply stuff
      in prtMarkerSuppliesTable (where types like 'staple' are defined)
    - the advantage of using the common table (among others) is that
      Finisher supplies show up in HP WJA and other fleet mgmt tools

(9) I like the current ImagingJob and ImagingJobTicket classes
