Apologies, after re-reading my response this sounds a bit harsh, which was not my intent. My point is just that we don't need to add another attribute - we already have one for this purpose... :)

>> If the "job-presets-supported" and/or "job-triggers-supported" attributes are settable using Set-Printer-Attributes, they must be listed in the "printer-settable-attributes-supported" attribute. Any limits to the sizes of the attributes are handled at request time through the "client-error-request-entity-too-large" status code - see section 4.1.3 of RFC 3380.
