Hi,<br><br>I agree w/ Mike about an Informative appendix in IPP Everywhere<br>that updates IPP/1.1 Implementor's Guide (RFC 3196) with a good<br>discussion of matching of (underspecified and overspecified) tags<br>for natural languages.<br>
<br>Glen - note that the IANA subtag registry was machine-generated<br>by Doug Ewell in collaboration with the actual ISO standard groups<br>that produced all the source tags - this registry was verified by folks<br>from Unicode Consortium, Microsoft, Google, and others active in<br>
the IETF LTRU WG - I was active for ten years in this IETF WG.<br><br>I would not characterize that IANA registry as "a mess" - it's used in <br>the message catalog and text processing software in a lot of operating <br>
systems and all major web browsers.<br><br>Tricky - yes - that's the point of lifting examples from RFC 4647 to<br>show the language tag matching rules in practice.<br><br>The list for printers of 50 common natural languages is useless - I've<br>
seen plenty of printers that support 100 or more.<br><br>But document DATA can be in any language (not just the console ones<br>in IPP generated-natural-language-supported) and UTF-8 or other<br>Unicode transcoding content can be correctly rendered using the<br>
correct glyphs for the script and language by printers from many <br>manufacturers.<br><br>Cheers,<br>- Ira<br><br><br>Ira McDonald (Musician / Software Architect)<br>Chair - Linux Foundation Open Printing WG<br>Secretary - IEEE-ISTO Printer Working Group<br>

I am not opposed to providing an example list of common language tags and
aliases, with a pointer to the IANA registry as the definitive source.
Ideally this should be part of an implementer's guide, but since I don't
think we want to update RFC 3196 it can go in a non-normative appendix that
references RFC 3196 as part of IPP Everywhere.<u></u><u></u><u></u><u></u></span></font></p>
