How can I set the address format:

var address = {};
address.Street = STREETNAME;
address.City = CITYNAME;
address.ZIP = ZIPCODE;
address.Country = 'Austria';

When I manually add an address in address book and select country 'austria', the state-field disappears and the zip is written before the cityname (as done in austria)

but setting the country via my app, formatting in incorrect.

is there an additional parameter? what are the properties of the address class?
