UK Core Implementation Guide 0.5.0

StructureDefinition Extension-UKCoreAddressKey

This carries an address key which will be included in an address.

Purpose

This extension extends the Address datatype to support the exchange of the type of address key and the address key value, which are currently not supported by the FHIR standard.

Context of Use
Use on element	Address
