WRT slide 5, during the IPP WG concall today the following question came up:
- What is meant by "non-IPP attributes"? Is it a vendor-specific attribute ("canon-foo", etc.), or is it out-of-band data associated with the named preset, or ???

And RFC 8011 places specific requirements on Client implementations WRT supporting all defined attribute syntaxes, including the collection attribute syntax used for job-presets-supported. So IMHO Client limitations are not a realistic concern for this attribute.

We can make this explicit in the definition of job-presets-supported if you like, but it isn't explicitly necessary since the definition of the attribute says that the collection contains Job Template attributes to be copied to the job creation request.
