The base definition for complex elements defined as part of a resource definition - that is, elements that have children that are defined in the resource. Data Type elements do not use this type,
though a few data types specialize it (Timing, Dosage, ElementDefinition).
For instance, Patient.contact is an element that is defined as part of the patient resource, so it automatically
has the type BackboneElement
.
Note that the descendant types of BackboneElement
are all declared implicitly as
part of the definitions of the resources.
