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?
