0. Extension
Definition

The Enclosed Precondition Extension allows for a precondition to be applied to an advance directive observation or goal. When applied to Goal instance, the stated goal only applies if the precondition is met. For example, the precondition 'If I am so sick or seriously injured that I cannot express my own medical treatment preferences' could be applied to the patient's goal of 'Avoiding prolonged dependence on machines'. When applied to an Observation instance, it is important to note that the precondition applies only to the preference expressed within the observation, not to the observation itself, since the act of recording the preference as an observation has already been done. For example, the precondition 'If I am nearing end of life' could be applied to the preference 'Please attempt to notify someone from my religion at the following number...' recorded within an observation.

2. Extension.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.
