Following up on my own post... Per the IPP workgroup meeting on June 4, 2020, the WG consensus is to remove section 11 from NODRIVER and add it as a future errata to IIG 2.0 with reference to the original 5100.13 for the figures/text.
TL;DR: We are moving section 11 to a future Implementor's Guide update.

In order to address this issue, we decided to add section 11, complete with examples covering the various edge cases.
>> Later when we updated RFC 2910 and 2911, I added the missing terminology and clarified the attribute definitions. Similarly, the other specifications that have caused issues in the past have been updated (PWG 5100.5, PWG 5100.7), are being updated (PWG 5100.3), or have been obsoleted (RFC 3381) so that we now have a consistent definition of terms and semantics across the board.
>> So after reviewing the section 11 content, I believe it is no longer necessary and might even be confusing to someone reading the current specifications since section 11 starts by saying that the various IPP specifications have slightly different definitions...
