Hi folks, Tuesday (30 January 2001)
For discussion on this mailing list and at tomorrow's IPP Telecon, here
is the proposed revised conformance from the IPP URL Scheme spec.
5. Conformance Requirements
5.1. Conformance Requirements for IPP Clients
IPP Clients that conform to this specification:
a) MUST send IPP URLs (e.g., in the "printer-uri" operation attribute
in 'Print-Job') that conform to the ABNF specified in section 4.4
of this document;
b) MUST send IPP operations via the port specified in the IPP URL (if
present) or otherwise via IANA assigned well-known port 631.
5.2. Conformance Requirements for IPP Printers
IPP Printers that conform to this specification:
a) SHOULD reject received IPP URLs in "application/ipp" request
bodies (e.g., in the "printer-uri" attribute in a 'Print-Job'
request) that do not conform to the ABNF for IPP URLs specified in
section 4.4 of this document;
b) SHOULD return IPP URLs in "application/ipp" response bodies (e.g.,
in the "job-uri" attribute in a 'Print-Job' response) that do
conform to the ABNF for IPP URLs specified in section 4.4 of this
document;
c) MUST listen for IPP operations on IANA-assigned well-known port
631.
d) MUST NOT listen for IPP operations on any other port, unless
explicitly configured by system administrators or site policies.
