according to http://en.wikipedia.org/wiki/Address_%28geography%29 , a standard address format would be

Format：
Person Name
Company name
Street
City area/District
City/Town/Village
County
Postal code
Country

for now Address datatype only have state,city,line.if i want to express it in China, two or three extensions will be added.it is a mess .why we just add district,town,village,county to Address datatype ,then let the implementer to choose how to populate this?
