Terminology

The terminology used in this CR should conform to the "Rules for the structure and drafting of International Standards", 5th Edition, 2005 available at:

http://isotc.iso.org/livelink/livelink.exe/fetch/2000/2122/3146825/4229629/4230450/4230456/ISO_IEC_Directives__Part_2__Rules_for_the_structure_and_drafting_of_International_Standards__2004__5th_edition___pdf_format_.pdf?nodeid=4230517&vernum=0

Particular attention shall be paid to Annex H which lays out guidelines for the expression of provisions.

Background/Rationale (Explanation of the background and reason(s) for the requested change, and supporting documentation):

As part of the PWG/DMTF Work Register, PWG is updating the printing-related classes in the CIM data model.

The PWG models for printing related devices and services include many properties that need to be managed but are not currently represented in CIM at all. The CIM model will be extended to include these important management objects. This will require extensions to the CIM_Printer class and the addition of other CIM classes to represent the capabilities, settings, and counters required.

Many early implementers of this class are expected to be proxy providers for SNMP-capable printers. A few properties in this class are included to permit software and users to correlate status and event information between CIM and legacy SNMP access paths. It is expected that such properties will be deprecated when they are no longer needed for this purpose.

The current new class, CIM_PrinterElement, is an abstract class from which all the major component classes of a printer will be derived, e.g., trays, markers, supplies, interpreters, channels, etc. Key data, and a legacy property required for correlation between external views of the various printer components, will be added at this level in the hierarchy.

       "This class extends LogicalElement to abstract the concept of a "
       "PrinterElement that is a component (e.g., PrintMarker) of a "
       "scoping Printer (print device). This class defines common "
       "properties for key (InstanceID) and for correlation of status "
       "and event (alert) information between CIM and SNMP management "
       "interfaces (SNMPRowId). Note: A PrinterElement shall be "
       "associated with exactly one Printer via an instance of the "
       "PrinterComponent class. See: Model in section 2 of Printer MIB "

          "to the <Schema Name>_<Class Name> structure of Schema class "
