Hi Glen,

CC to WIMS list - as yours is a good question.

The intended element grouping is show below
- based on System versus Admin control of each
of the elements.

[As I said during yesterday's WIMS telecon,
I'll be writing a mostly outline initial draft of
the PWG Power Management Model spec
in the next few weeks (before August F2F).]

For DMTF CIM MOF, PWG XML Schema, and
PWG Power Management MIB, the elements
should be grouped as follows:

Status - all READ-ONLY properties set by System

REQUIRED - Power Monitor Group
  (simple state elements)
OPTIONAL - Power Log Group
  (table of power-related events)

Capabilities - all READ-ONLY properties set by System

REQUIRED - Power Mode Group
  (table of supported states/power usage levels)
REQUIRED - Power Transition Group
  (table of supported state transitions/durations)

Settings - all READ-WRITE properties set by Admin

OPTIONAL - Power Policy Group
  (table of local site policies for power transitions)
OPTIONAL - Power Request Group
  (operation to transition to a new power state)


NOTE:  PowerMode.IsAcceptingJobs (a capability)
is NOT settable by the Admin.  Instead, each element
XxxService.IsAcceptingJobs is settable by the Admin.

Cheers,
- Ira
