Hi,

I have just posted another Interim draft of IPP System Service for
review during the IPP WG meeting today:

  http://ftp.pwg.org/pub/pwg/ipp/wd/wd-ippsystem10-20150831-rev.pdf
  - PDF with line numbers and redlines

  http://ftp.pwg.org/pub/pwg/ipp/wd/wd-ippsystem10-20150831-rev.docx
  - MS Word source with line numbers and redlines

This draft contains all of the proposed changes from the PWG F2F
review on 10 August 2015.

This draft contains a *complete* list of proposed operations for the
new IPP System and Resource objects, including the proposed
conformance.  This draft also contains a *complete* list of proposed
attributes for the new IPP System and Resource objects, including
the proposed conformance.

Cheers,
- Ira
