[Issue Unconfirmed]
The definition of the Get-System-Attributes operation on page 70
(http://ftp.pwg.org/pub/pwg/candidates/cs-ippsystem10-20191122-5100.22.pdf#page=70)
doesn't clearly state whether the System object can or must not challenge
the Client for authentication. It has been asserted that the semantics of
the Get-System-Attributes operation should match Get-Printer-Attributes in
that the System object MUST NOT challenge a Client for authentication in
response to a Get-System-Attributes operation request.
Add text to clarify the expectations, such as "The System MUST NOT
challenge the Client for authentication in response to a
Get-System-Attributes request."
