8. Extension.value[x].type
Definition

Distinguishes between physical addresses (those you can visit) and mailing addresses (e.g. PO Boxes and care-of addresses). Most addresses are both.

Shortpostal | physical | both
Comments

The definition of Address states that "address is intended to describe postal addresses, not physical locations". However, many applications track whether an address has a dual purpose of being a location that can be visited as well as being a valid delivery destination, and Postal addresses are often used as proxies for physical locations (also see the Location resource).

Comments

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
