/// MessageDefinition defines the characteristics of a message that can be
/// shared between systems, including the type of event that initiates the
/// message, the content to be transmitted, and what response(s), if any, are
/// permitted. In FHIR R5 messaging, information is exchanged as a Bundle whose
/// first entry is a MessageHeader; MessageDefinition is the canonical,
/// conformance-style artifact that describes the expected shape of such an
/// exchange for a particular triggering event. It specifies the event code (or
/// EventDefinition) that initiates the message, the focal resources that form
/// the message payload together with their profiles and cardinality, whether a
/// response is required, and which response messages are allowed in return.
///
/// MessageDefinition is used primarily at design and conformance time rather
/// than at runtime: implementers and integration engines publish and consume
/// MessageDefinitions to advertise, discover, and negotiate the messages that
/// systems can send and receive, and to validate that an actual message
/// conforms to an agreed contract. Being a canonical resource, it carries
/// standard metadata such as url, version, status, and publisher so it can be
/// referenced stably across implementation guides and registries.
///
/// See also: the focal payload details are held in
/// [`MessageDefinitionFocus`], the permitted replies in
/// [`MessageDefinitionAllowedResponse`], event categorization uses
/// [`Coding`](crate::r5::types::Coding), and jurisdictional scope uses
/// [`CodeableConcept`](crate::r5::types::CodeableConcept). Related messaging
/// artifacts include the `MessageHeader`, `EventDefinition`, and
/// `GraphDefinition` resources.
///
/// # Examples

/// use fhir::r5::resources::message_definition::MessageDefinition;
///
/// let value = MessageDefinition::default();
/// let json = ::serde_json::to_value(&value).unwrap();
/// let back: MessageDefinition = ::serde_json::from_value(json).unwrap();
/// assert_eq!(value, back);
