Hi Konstantin,
I finalized the change of sub-type to type for i18n:number
and introduced the code again for yet missing types
(int-currency, currency-no-unit, int-currency-nu-unit)
As new attribute I added fraction-digits="..."
for i18n:number so we can now print out
gasoline prices etc.
Regards,
Michael
