I have too little experience with standardisation to comprehend that,
I'm afraid.  Sorry if I see it too trivially, but: The documented
basis for distinction is the normative guide where the respective
language is described, isn't it?  And the distinction is appropriate
where otherwise invalid output would be generated.

I'll give an example for what I mean.

I begin an XML letter with
   <letter xml:lang="de-AT">
and the XML-processor inserts a "31. Jšnner 2002", whereas
   <letter xml:lang="de-DE">
yields "31. Januar 2002" in the first line of the Postscript.

If the processor also created an envelope according to mailing system
rules of the FR Germany (e.g. with a barcode), *this* would be a real
locale issue, handled maybe by a configuration file.  But the date is
part of the letter and depends on the language, may it be generated or
not.

Another example: A text in French must be printed with tiny spaces
before every "!" and "?".  In German and French there is no extra
space after a sentence.  Etc.

All these things are implicit behaviour of the processing software and
depend on a precise language tag.


To sum it up: "de-DE-1996" means "German using new orthography".  What
the software or whatever makes out of this info, is only its own
business.  It can perfectly ignore it, or use it to produce a decent
result.  But in my opinion the message itself is totally unambiguous.

Bye,
Torsten.
