/// A definition of a condition and information relevant to managing it.
///
/// ConditionDefinition is a canonical, knowledge-artifact style resource that
/// describes a clinical condition, problem, or diagnosis independent of any
/// single patient or encounter. Rather than recording that a particular person
/// currently has a condition, it captures reusable knowledge about the condition
/// itself: the identifying code, the subjective severity, the anatomical body
/// site, and the stage or grade, together with metadata flags indicating whether
/// severity, body site, and stage are appropriate to record for this condition.
/// It also links to the observations and preconditions that are diagnostically
/// relevant, the medications commonly used, the questionnaires used for
/// pre-admission, differential diagnosis, or outcome assessment, the care teams
/// suited to managing it, and the care or treatment plans that apply.
///
/// In FHIR R5 a ConditionDefinition acts as a definitional resource that drives
/// clinical decision support, standardized data capture, and consistent
/// recording of patient-specific condition instances. Authoring systems and
/// registries publish these definitions so that downstream applications can
/// prompt for the right data and validate recorded conditions against agreed
/// guidance.
///
/// See also the patient-specific [`Condition`](crate::r5::resources::condition::Condition)
/// resource that a definition informs, the [`Patient`](crate::r5::resources::patient::Patient)
/// it is ultimately recorded against, and related definitional and supporting
/// resources such as [`Observation`](crate::r5::resources::observation::Observation),
/// [`Questionnaire`](crate::r5::resources::questionnaire::Questionnaire),
/// [`CareTeam`](crate::r5::resources::care_team::CareTeam), and
/// [`PlanDefinition`](crate::r5::resources::plan_definition::PlanDefinition).
/// Many of its fields use the shared [`CodeableConcept`](crate::r5::types::CodeableConcept)
/// data type.
///
/// # Examples
///
/// ```
/// use fhir::r5::resources::condition_definition::ConditionDefinition;
///
/// let value = ConditionDefinition::default();
/// let json = ::serde_json::to_value(&value).unwrap();
/// let back: ConditionDefinition = ::serde_json::from_value(json).unwrap();
/// assert_eq!(value, back);
