0. Extension
Definition	Fyysisen toimituksen (esim. mittarin postitus) osoite- ja yhteystiedot digisovellusmääräyksessä. Mallinnetaan määräyksen omana laajennuksena, ei Patient-resurssin address/telecom-tietoina, jotta toimitustieto pysyy määräyskohtaisena ja voi poiketa potilaan kotiosoitteesta. Koko laajennus ja sen alaelementit (address, phone, email) ovat valinnaisia. Optional Extension Element - found in all resources.

4. Extension.extension:address.extension
Definition	An Extension May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
Short	ExtensionAdditional content defined by implementations
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.

52. Extension.extension:email.value[x].extension
Definition	May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
Short	Additional content defined by implementations
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.
