Okay, that's reasonable. But your reading is a little like saying "application/vnd.hp-PCL" is a supported document-format value for "text/plain" Jobs.

So what we have here is a Printer Description Attribute (PDA) which is invariant with respect to document-format. Are there other PDAs that should be considered invariant? printer-name? printer-state? printer-is-accepting-jobs? pdl-override-supported? color-supported? Or can these be considered attributes of a particular interpreter in a Printer? Maybe only Printer Job Template attributes are a function of document-format?
