This case-sensitive code system http://hl7.org/fhir/reference-handling-policy defines the following codes:
Code
Display
Definition
literal
Literal References
The server supports and populates Literal references where they are known (this code does not guarantee that all references are literal; see 'enforced')
logical
Logical References
The server allows logical references
resolves
Resolves References
The server will attempt to resolve logical references to literal references (if resolution fails, the server may still accept resources; see logical)
enforced
Reference Integrity Enforced
The server enforces that references have integrity - e.g. it ensures that references can always be resolved. This is typically the case for clinical record systems, but often not the case for middleware/proxy systems
local
Local References Only
The server does not support references that point to other servers
