The spec says:
The language is used to select the appropriate language-dependent forms of:
names (for example, of months)
numbers expressed as words or as ordinals (twenty, 20th, twentieth)
hour convention (0-23 vs 1-24, 0-11 vs 1-12)
first day of week, first week of year
It isn't used to select what family of digits to use; that's done using
the format token, for example D01 requests ASCII digits. In many
languages, for example in business or scientific writing, western digits
are often used in place of "native" digits, so the desired language is
not a good way of selecting what digit family to use. (See here for
example: http://www.banmuang.co.th/)

I'm having a hard time decyphering the specs for the new XQuery 3.0
fn:format-dateTime when it comes to numeric values.
In particular, if you pass a language argument does that take
precidence over or affect at all numeric values.
E.g. what is the expected result of this :
fn:format-dateTime(xs:dateTime("1996-08-30T23:35:09.12-09:00"),"[Y]","hi","AD","US"),
1996 or 1996
And this
fn:format-dateTime(xs:dateTime("1996-08-30T23:35:09.12-09:00"),"[Y01]","ar","AD","AE")
96 or 97
In the text for
http://www.w3.org/TR/2011/WD-xpath-functions-30-20111213/#func-format-dateTime
I don't find any description on how language affects numeric values,
or on if the digit values have higher or lesser precidence then the
values.
But this example:
Jewish (with Western numbering)
format-date($d, "[D] [Mn] [Y]", "he", "AM", ())
?26 ??? 5763
Jewish (with traditional numbering)
format-date($d, "[Dאt] [Mn] [Yאt]", "he", "AM", ())
?"? ??? ???"?
Implies that language with no format digits should be western,
and that format digits override language codes.
Any suggestions on how to clarify this in partiular a refence to the
spec where the rules are defined. I'm sure I missed something.
I do read this:
The language is used to select the appropriate language-dependent
forms of:
names (for example, of months)
numbers expressed as words or as ordinals (|twenty, 20th, twentieth|)
hour convention (0-23 vs 1-24, 0-11 vs 1-12)
first day of week, first week of year
To me this implies that languages has no effect at all on numeric
formats. This is consistant with the example, but thats only by
exclusion not inclusion of wording.
Thanks for any suggestions.
