Examples of xsl:format-number() with ICU?

[Nick Bastin]

Does anybody have any examples of using xsl:format-number() with ICU 
support?  I'd like to just tell it what locale I'm using, but it 
appears that we have to pass the number formats into the source XML 
file so that we can pass the right number format to the function.  Is 
this the way people do it, or am I missing something obvious?
