+ Warning: Name should be usable as an identifier for the module by machine processing applications such as code generation
+ Rule: Element paths must be unique unless the structure is a constraint
+ Rule: If the first element in a differential has no "." in the path and it's not a logical model, it has no type
+ Rule: If the structure is not abstract, then there SHALL be a baseDefinition
+ Rule: If the structure defines an extension then the structure must have context information
+ Rule: A structure must have either a differential, or a snapshot (or both)
+ Rule: In any snapshot or differential, no label, code or requirements on an element without a "." in the path (e.g. the first element)
+ Rule: If there's a type, its content must match the path name in the first element of a snapshot
+ Rule: All element definitions must have an id

For all FHIR defined types, the path name of the element will start with the type name. For logical models, where the type is a URL, the type name SHOULD start with the tail of the type URL where required.",
