JMF message size
MIME messages are supported in both chunked and non-chunked transfer encoding (HTTP/1.1) without a size threshold.
JDF ticket size
For non-JMF channels, the maximum supported ticket size is 4MBytes. Tickets larger than 4 MB are ignored.
JMF channels have no size limitation for the JDF ticket.
If a setting in the JMF message or in the JDF ticket is not supported, it is ignored.
If a setting or a value has a syntax which deviates from the JDF schemas, it is ignored.
The JDF ticket needs to be in correct XML according to the JDF 1.3 specification.
If the ticket cannot be parsed, error 3 (‘XML parser error’) will be sent in response to the JMF message SubmitQueueEntry.
Remark
A best effort is made to return an error in case the ticket cannot be executed. However, in case of specification contradiction, no error might be reported and the output may differ from the ticket intent.
For example: Stapling icw output HCS may result in a stapled job to a different output location.
