draft-ietf-ipp-implementers-guide-01 says:
job-media-sheets (integer(0:MAX))
IF NOT any single 'integer' value equal to 4 octets,
REJECT/RETURN 'client-error-bad-request'.
IF NOT in the range of the Printer object's "job-media-supported"
attribute, copy the attribute and the unsupported value to the
Unsupported Attributes response group and REJECT/RETURN
'client-error-attributes-or-values-not-supported'.
Shouldn't that be "job-media-sheets-supported", not "job-media-supported"?
