[Just sent with wrong subject line for the companion MIB - sorry about that]

I've just posted a Stable draft of the PWG Power Management Model, ready
for WIMS WG last call:

 ftp://ftp.pwg.org/pub/pwg/wims/wd/wd-wimspower10-20100926.pdf / doc
 - clean copy with line numbers

 ftp://ftp.pwg.org/pub/pwg/wims/wd/wd-wimspower10-20100926-rev.pdf / doc
 - redlines with line numbers

This draft addresses all the comments from the WIMS WG review last week.

This document is technically aligned with PWG Imaging System Power MIB.
