[Printing-architecture] OPVP specification and use of UPDF

At today's architecture meeting, we discussed the proposed OPVP 
specification in it's current form.  We discussed the issue with the 
method of describing properties that was brought up at the last 
OpenPrinting SC meeting.  The issue is that the specification does not 
require a conforming implementation to support a specific scheme, but 
instead simply states that the implementation can support any scheme it 
likes.  The specification goes on to use UPDF as an example.

What we are looking for is a statement in the specification that selects 
a required scheme to facilitate standard
description of properties so that there is a known method of specifying 
properties.  Without this, it becomes less likely that renderers and 
drivers will be able to be used outside of the specific renderer or 
driver that they were designed to be used with.

We would appreciate it if someone would come to the OpenPrinting 
Steering Committee meeting next week prepared to respond to this.  Once 
this is addressed, we can move forward with the process.
