RE: [xsl] Different results of format-date() when using empty seq. or omitting args for lang/cal/country args

It turns out in fact that if you call format-date() with two arguments,
Saxon defaults the language to:

* the language of the default Java locale provided that there is a Saxon
localization for this language

But if you supply () as the value of the third argument, Saxon defaults the
language to:

* the language of the default Java locale whether or not there is a Saxon
localization for this language

The default should be the same in both cases, I will fix this.

(I did some interesting but not very successful experiments trying to
configure my PC to use Dutch. All I achieved was to select a US keyboard
mapping, which doesn't match the keys on my keyboard...)
