Job description is split in two parts:
Job template attributes
XPIF operations attributes
The operations attributes are not used for processing, but give information about the job (like job name, job size…). Generally, these attributes are also given by the submission protocol. When operations attributes are specified in the XPIF ticket, the concerning protocol settings are overwritten.
