Name Flags Card. Type Description & Constraints doco
. . StructureDefinition I DomainResource Structural Definition
If there's a constrained type, its content must match the path name in the first element of a snapshot
If the structure defines an extension then the structure must have context information
element.base cannot appear if there is no base on the structure definition
A structure must have a base unless abstract = true
element.base must appear if there is a base on the structure definition
If the structure describes a base Resource or Type, the URL has to start with "http://hl7.org/fhir/StructureDefinition/" and the tail must match the id
A structure must have either a differential, or a snapshot (or both)
Element paths must be unique unless the structure is a constraint
In any snapshot or differential, all the elements except the first have to have a path that starts with the path of the first + "."
In any snapshot or differential, no label, code or requirements on the an element without a "." in the path (e.g. the first element)
If the structure is not abstract, or there's a constrained type, then there SHALL be a base
