Hello, ( dobry den )

check out the recent past archives in EXSLT, we have been discussing such things

but in general there is an EXSLT definition, which is admittedly underpowered.

if u are discussing in xslt, I would suggest looking at the http://fxsl.sourceforge.net/articles/Random/Casting%20the%20Dice%20with%20FXSL-htm.htm

Thanks, Jim. This looks like what we need.
Petr
