Hi Hugo,

Thanks for the quick and thorough response.

Let me comment on 'natural-language-configured'.  Like ALL of
the IPP-derived attributes in the SLP 'printer:' template, it
is meant to accurately reflect the actual configuration of
the IPP Printer object.  However, since SLP (and LDAP) don't
have any standard base datatype 'textWithLanguage', the
'natural-language-configured' attribute does double duty
to specify the language of SLP (and IPP Printer object)
attributes with 'textWithLanguage' or 'nameWithLanguage'
(such as site-administered media names, which are very
important in enterprise printing environments).

This is conformant with RFC 2277 (IETF Policy on Charsets
and Languages) which MANDATES that all application protocols
which transfer text shall explicitly convey the language
of that text.  It is NOT optional for an IETF standards-track
document to put language-tags on text attributes.  It is 
a requirement to stay on the Internet 'standards track'.

We COULD have a separate attribute for the language
of the SLP 'printer:' template text and site-name
attributes, but it seems an entirely reasonable simplification
to presume that a system administrator would: 1) install
a network printer (connectivity setup); 2) set the
'natural-language-configured' of that printer; and 3) set
various site-specific info attributes of that printer.
So the current SLP 'printer:' template makes sense.

What do you think?
