    How about the following:

         1. Put the non-document object stuff into a separate IPP
            extension spec (I think that would just be the changes
            to Get-Jobs - I'll review to see if there are others)
         2. Remove the REQUIRED status from the URI-based document
            operations and publish the document object spec (with
            any other changes that come up after reviewing it)
         3. Publish a new PSI spec which adds additional requirements
            for IPP conformance in a PSI environment; this spec would
            reference all of the applicable IPP documents and provide
            "one-stop-shopping" for someone that wanted to determine
            conformance for PSI.

    No matter what way we go, I still think we'll need another round
    of document review before we go to last-call and voting.
