No, this was for GetAttributes and GetJobs which should report OK and
return unsupported attributes with a value of 'unsupported'.
In the case of print submission with "should-honor-attributes", the
server hopes it can honor, but it doesn't know what it will fail on.

Maybe once we have the protocol better defined we will know whether this
is a possibility, but I would expect the printer wait for the disk-full
condition to go away. Then it would write the data and return a response
of success. If it returns this message instead, then the client has to
go into some recovery mode which makes the client more complicated.

The PrintJob has a limit of one document. CreateJob/SendJobData should
have no job limit. It may have an octet-limit for an entire job.
