I can't remember if the request-id is the same as a request
"transaction-id", but if it is, the server never validates this field. It =
set by the client and echoed back by the server in the corresponding
response. There is no validity check made by the server (that I am aware

Suppose the Printer object, while parsing an IPP requests, fails to =
the "request-id" in the incoming payload (because the packet was incomplete=

or because the value is not between 1 and 2**31-1). The documents =
that the Printer object should return a 'client-error-bad-request' status
code. That's fine; now my question: What request-id should the Printer
object include in the response (I'm assuming that responses with error
status codes must also include version, request-id, charset, etc.)? =
0 be used to handle this cases?
