/// Identifier is a FHIR R5 complex datatype that identifies some entity
/// uniquely and unambiguously. It is most commonly used to carry business
/// identifiers such as medical record numbers, order numbers, and driver's
/// license numbers, distinguishing them from the technical logical identifiers
/// assigned by FHIR servers. Each Identifier can pin the value to a namespace
/// via `system`, classify its role via `use` and `type`, and record the period
/// of validity and the organization that assigned it.
///
/// # Examples
///
/// ```
/// use fhir::r5::types::identifier::Identifier;
///
/// let value = Identifier::default();
/// let json = ::serde_json::to_value(&value).unwrap();
/// let back: Identifier = ::serde_json::from_value(json).unwrap();
/// assert_eq!(value, back);
/// ```
