Component Structure
Components	Name	Description of Element Role	Cardinality	Data Type

	| MessageThreadId	A xs:string used to uniquely identify the thread of Messages of which the current Message is a part. The MessageThreadId shall be, in combination with the DdexPartyId (DPID) of the MessageSender, globally unique. Thus, a MessageSender shall never re-use a MessageThreadId. One example of such a 'thread' is the chain of NewReleaseMessages being sent from ReleaseCreator to wholesale ReleaseDistributor 1 to retail DSP when communicating information about the same Release(s). A common MessageThreadId will allow all these messages to be tied together.	0-1	String (xs:string)
