In Roger's recent comments to Don's latest REQ draft:

True, view printer capabilities is quite essential.  However, since this
section of the document attempts to enumerate functions (rather than just
describing them in prose form), viewing status and viewing capabilities
should be two separate lines in the enumeration list.

Absolutely.  The statement of "altering the *status* of the job" has come
up frequently in the near past, and these words should be changed to
reflect reality.  Thanks for pointing this out, Roger.

Hmm...  This sends up a couple of red flags to me.  Is IPP specifically
directed to solve only the needs of the Enterprise, or is IPP supposed to
equally apply to SOHO and home (ie, consumer) environments?  SOHO/consumer
environments typically do not have system administrators.

> Section 2.1.3 Viewing the status of a printer
> Change the title to Viewing the status and capabilities of a printer.

Similar to the comment near the top, these two features should be described
separately.  A user might first query the capabilities of the printer before
submitting a print job (in which case the status may not be relevant), and
then query the printer for status after the job has been submitting (in which
case the printer's current capabilities are irrelevant).

Considering the schedule, we should probably opt to simply state that the
functionality "includes, but is not limited to" that presented in the list.

So much for protocol independence for IPP...  ;-)
