In the Job Template Attributes there are attributes
that can be a type3 keyword or a name (job-hold-until,
job-sheets, and media). As I read the spec, these
attributes are usually type3 keywords but can optionally
be changed at the printer to a name type. Is this
correct or did I miss something in the spec?
My question is how does an IPP client know which
type to send? If the wrong type is sent, what should
the expected reply be?
