1. Address
Definition	An address expressed using postal conventions (as opposed to GPS or other location definition formats). This data type may be used to convey addresses for use in delivering mail as well as for visiting locations which might not be valid for mail delivery. There are a variety of postal address formats defined around the world.
Control	0..* This element is affected by the following invariants: ele-1
Comments	Note: address is intended to describe postal addresses for administrative purposes, not to describe absolute geographical coordinates. Postal addresses are often used as proxies for physical locations (also see the Location resource).
Invariants	Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
2. Address.use
Definition	The purpose of this address.
Control	0..1
Binding	The codes SHALL be taken from AddressUse The use of an address.
Type	code
Is Modifier	true
Summary	true
Requirements	Allows an appropriate address to be chosen from a list of many.
Comments	Applications can assume that an address is current unless it explicitly says that it is temporary or old.
Example	General:home
Invariants	Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
3. Address.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.
Control	0..1
Binding	The codes SHALL be taken from AddressType The type of an address (physical / postal).
Type	code
Summary	true
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).
Fixed Value	postal
Example	General:both
Invariants	Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
