description: This profile represents personal health goals, preferences, and priorities for medical treatments or interventions in the event of a future health scenario where a person is unable to make medical decisions because of a serious illness or injury. To promote interoperability and adoption through common implementation, this profile sets minimum expectations for the Observation resource to record, search, and fetch for a patient's treatment intervention preferences. This profile identifies which core elements, extensions, vocabularies, and value sets **SHALL** be present in the resource and constrains the way the elements are used when using this profile. It provides the floor for standards development for specific use cases.
