While I acknowledge this may be true for general IPP printing, the device ID is not needed for IPP Everywhere since we have higher-level PDLs that respect Job Template attributes. And in the case of PWG Raster, the pwg-raster-document-xxx attributes are used by a Client to produce a compatible raster stream, *not* the 1284 device ID.

Basically, although I'd like to just remove the references in the IPP Everywhere specification and let the original definition in PWG 5107.2 stand for vendors that want to support the attribute.
