(8) PWG Process Updates

* Including Best Practices and Requirements documents in the numbering system
-- Update to "pwg-namespace-policy.txt" in development

* Process v4.0 still a work in progress

(9) Process v4.0

* Original notion: Update existing Process 3.0 to merge in subsequently published PWG 
  policy documents
-- pwg-policy-call-for-obj-last-call-formal-vote-draft-2.txt (draft)

-- ipp-registry-policy.txt

-- pwg-billing-policy-20141001.txt

-- pwg-white-policy-20140505.txt

-- pwg-charter-policy-20140407.txt

-- pwg-prototype-policy-20121029.txt

-- pwg-namespace-policy-20160820.txt (new updated draft)

* Revised notion: Refactor the Process document to describe the processes of the PWG 
  to make them simple and obvious to the uninitiated reader:
-- Proposing new work to the PWG

-- Approving new work and assigning to a PWG work group

-- PWG approval for various document types
--- Whitepaper

--- Standards-track

--- etc.

ACTION: 08/28/19 - Smith/Ira to start a new thread on Process 4.0 framework
- OPEN

(10) Design Principles Whitepaper

* Purpose:
-- A document that describes the PWG's core tenets and design principles that guide the 
   design and creation of its IPP, Semantic Model, MIBs, and other technologies

* Scope / Topics to be Covered:
-- IPP
--- Late binding principle

--- Intent vs. process for Job fidelity

--- Value of separating Job attributes from Document content

--- IPP attribute types and design patterns
---- Printer Status vs. Printer Description

---- xxx / xxx-supported / xxx-default vs. xxx / xxx-configured / xxx-supported

---- Collections vs. textual encoding of MIB sequences ("printer-finisher")

-- Semantic Model
--- Creates comprehensible view of the elements in an Imaging System, allowing better 
    communication with other standards organizations dealing with related matters.

--- Presents the basic features necessary in communicating with Imaging Services, 
    independent of the protocols used in that communication

--- Allows exploitation of the inherent parallelism between different types of Imaging 
    Services (Print, Scan, Fax, etc.)
