0. Extension
Definition	An advance healthcare directive attester is a person (typically a witness or notary) who formally verifies and confirms that an individual has voluntarily signed an advance healthcare directive—a legal document outlining their wishes for medical treatment if they become unable to communicate those decisions themselves. The attester's role is to authenticate that the directive was executed properly, that the signer appeared competent, and that no undue influence or coercion was involved. Optional Extension Element - found in all resources.

4. Extension.extension:mode.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.

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.
