the current PostalAddress Enity will be supplemented Address Schema Change Proposal by new entities that deal with expanded information.

The Country entity might be tied into the Geocode. You can have different Mailing structures in a country
most of this specification is calling out how to create an address for different Countries.
in the way ofbiz works Country would be used to define the layout of a countries address. both in the UI and in how the data is added to the PostalAddress data.

There are three basic ways to specify a Mailing address in a country.

1)AdministrativeArea entity covers more general information that allows non specific data to help identify and locations.
2)The Locality entity 
3)Thoroughfare Entity

Premise would be a Facility Entitiy for a building like office complex or Apartments. it is more for doing searches to validate the address.

- APT - Apartment
- LOT - Lot
- RM - Room
- SLIP - Slip
- SUIT - Suite
- UNIT - Unit Identification
- FLR - Floor
- BLDG - Building
- PIER - Pier
- WNG - Wing

so a premise Lot can have children Premise BLDG that an have children Premise Flr

 AddressDetails entity incorporates locality and premise entities.

PostalService entity convers Postoffice information used for bulk mailing

 The US Postal rules is the Top line should be for Attn to or Company name. The Line closest to the city, Postallocal should have the delivery info address line.

not in entity format but this will show how the formating would be called out in a simple form

the fmt would read by the UI code to put the input in the right sequence horzontally and veritically.
