Added to which, the implementors of the operating systems we have to use
don't even seem to be able to agree on how to implement "locale" at the
OS level.

When I first saw it, I assumed it meant "A-Z as specified in ASCII
or ISO 646RV", this being the most obvious sequence of characters
known to work on all machines, despite it being entirely the wrong
sequence for at least 30% of the work I do.

I think having xsl:number open to arbitrary reinterpretation on the
basis of the locale would be a serious error: there would need to be
some way to specify up front which sequence is to be used.

So far as I am aware, ordered lists which use alphabetic labels in
non-English Latin-alphabet languages never use diacriticals (but I'm
happy to be corrected). This is probably a cultural inheritance from
an older period when text was written in Latin, where there was a
relatively stable alphabet.
