I have specifically avoided suggesting that we add a job-client-id job
attribute because it would have to be mandatory in order to offer a
solution to an LPD-to-IPP gateway. I don't think it is reasonable for
all implementations to support such an attribute, and I don't want to
support it for an IPP-to-LPD gateway because the gateway would then
have to maintain state for a client that sends it to the IPP-to-LPD
gateway.
