localised picture string for format-date

Hi,

Is there a simple way for format-date() to output a localised date format?

For example, given xs:date("2009-06-13") and a picture string of
"[D01]-[M01]-[Y0001]", is it possible to supply a country code such as
"US" and have month-day-year output?  Or do you need to define each
picture string yourself, and choose the right one based on a supplied
country code?

(the country code parameter to format-date() doesnt appear to do that)



thanks
