> James and Erik beat me to where I was heading.  As an SLP_API user, I
know that a natural language must be specified with each SLP registration
and request, independently of the type of service being
registered/searched.  It seems to me then that both SLP and IPP have
already conformed with RFC 2277; SLP by requiring the natural language
associated with each SLP request/query (regardless of the template being
used) and IPP by supporting 'natural-language-configured' in its object

IPP also requires "attributes-natural-language" on every request and
"natural-language-configured" is a default that MUST be overridden on every
request.  It's only used when a Printer receives a request in a natural
language it doesn't support.

> It would appear then that the reason for having
'natural-language-configured' and 'natural-language-supported' in the
'printer:' template is mostly for convenience, so users can get to that
information without making an additional request to the printer (and as I
indicated in my previous message, I question how useful that feature really

IPP doesn't have 'natural-language-supported', only
"generated-natural-language-supported".  An IPP Printer MUST accept any
natural language and any Natural Language Override, whether the IPP object
supports that natural language or not.
