/// A set of healthcare-related information that is assembled together into a
/// single logical package.
///
/// A Composition establishes a single coherent statement of meaning, defines
/// its own context, and carries clinical attestation regarding who is making
/// the statement. It provides the structure and narrative content necessary for
/// a clinical document, organized into sections. In FHIR R5 a Composition alone
/// does not constitute a document; it is typically the first entry in a Bundle
/// of type "document" that packages the referenced resources together.
///
/// Compositions are used to represent discharge summaries, consultation notes,
/// diagnostic reports, care plans, and other attested clinical or administrative
/// documents. Each Composition has exactly one `subject` context (commonly a
/// patient) though implementations may reference multiple related subjects, a
/// responsible `author`, a `status` reflecting its lifecycle, and one or more
/// `section` elements that hold the narrative and referenced entries making up
/// the body of the document. Once a Composition is part of a signed or attested
/// document, its content is generally considered immutable; a new `version` or a
/// document addendum is used to record subsequent changes.
///
/// # Related resources
///
/// A Composition typically references a [`Patient`](crate::r5::resources::patient::Patient)
/// or other resource as its subject, is authored and attested by practitioners or
/// organizations via `Reference`, and classifies its type and section codes using
/// [`CodeableConcept`](crate::r5::types::CodeableConcept). See also the `DocumentReference`
/// and `Bundle` resources, which are commonly used together with Composition to
/// index and package a complete clinical document.
///
/// # Examples
///
/// ```
/// use fhir::r5::resources::composition::Composition;
///
/// let value = Composition::default();
/// let json = ::serde_json::to_value(&value).unwrap();
/// let back: Composition = ::serde_json::from_value(json).unwrap();
/// assert_eq!(value, back);
