constraints of the IPP/1.1 separate attributes.
Defined keywords for fields include:
’uri’ (IPP ’printer-uri-supported’)
’auth’ (IPP ’uri-authentication-supported’)
’sec’ (IPP ’uri-security-supported’)
A missing ’auth’ field should be interpreted to mean ’none’. Per
IPP/1.1 [RFC2911], defined values of the ’auth’ field include:
’none’ (no authentication for this URI)
’requesting-user-name’ (from operation request)
’basic’ (HTTP/1.1 Basic [RFC2617])
’digest’ (HTTP/1.1 Basic, [RFC2617])
’certificate’ (from certificate)
A missing ’sec’ field should be interpreted to mean ’none’. Per
IPP/1.1 [RFC2911], defined values of the ’sec’ field include:
’none’ (no security for this URI)
’ssl3’ (Netscape SSL3)
’tls’ (IETF TLS/1.0, [RFC2246])
Each XRI field should be delimited by ’<’. For example:
’uri=ipp://foo.com< auth=digest< sec=tls<’
’uri=lpr://bar.com< auth=none< sec=none<’
’uri=mailto:printer@foobar.com< auth=none< sec=none<’
Note: The syntax and delimiter for this attribute are aligned with
the equivalent attribute in the ’service:printer:’ v2.0 template
[SLP-PRT]. Whitespace is permitted after (but not before) the
delimiter ’<’. Note that this delimiter differs from printer-
resolution-supported.
Note: See Sections 1.1, 1.2, and 1.3 for rationale for design
choices.

Values of this attribute should be specified in the language
specified in printer-natural-language-configured (for example, to
support text-to-speech conversions), although the printer’s name may
be specified in any language. This name may be the last part of the
printer’s URI or it may be completely unrelated. This name may
contain characters that are not allowed in a conventional URI (see
[RFC2396]).
4.4. printer-natural-language-configured

Also, a possible natural language for printer string attributes set
by operator, system administrator, or manufacturer. Also, the
(declared) natural language of the printer-name, printer-location,
printer-info, and printer-make-and-model attributes of this printer.
Values of language tags should conform to "Tags for the
Identification of Languages" [RFC3066]. For example:
’en-us’ (English as spoken in the US)
’fr-fr’ (French as spoken in France)
For consistency with IPP/1.1 [RFC2911], language tags in this
attribute should be lowercase normalized.

For example, this could be an HTTP type URI referencing an HTML page
accessible to a Web Browser. The information obtained from this URI
is intended for end user consumption.
Values of URI should conform to [RFC2396], although URI schemes may
be defined which do not conform to [RFC2396] (see [RFC2717] and
[RFC2718]).
Note: LDAP application clients should not attempt to use malformed
URI values read from this attribute. LDAP administrative clients
should not write malformed URI values into this attribute.
Note: See Sections 1.1, 1.2, and 1.3 for rationale for design
choices.

Also, a possible charset for printer string attributes set by
operator, system administrator, or manufacturer. For example:
’utf-8’ (ISO 10646/Unicode in UTF-8 transform [RFC2279])
’iso-8859-1’ (Latin1)
Values of charset tags should be defined in the IANA Registry of

Each resolution value should be a string containing 3 fields:
