Which mechanism is used to attach controlled vocabularies to data elements in FHIR?

Explanation:
Terminologies provide the mechanism to bind data elements to controlled vocabularies. In FHIR, a data element can be bound to a ValueSet (which references one or more CodeSystems like LOINC or SNOMED-CT). This binding enforces the codes that may be used for that element, ensuring consistent interpretation across systems. Profiles constrain structure and cardinality, Extensions add extra data, and Security relates to access control.
