To add a technical mechanism that supports getting the "most recent" version.

Use Case: to construct a resource it's often required to retrieve the most recent version of underlying value sets. Some of them are too big to pull them every time when a resource is created. It's better to cache the value set on the "resource generator" side and check if a newer ValueSet is available on the Terminology Server and GET ValueSet only if the newer version has been published.

E.g.: GET <base>/ValueSet?title=AdministrativeGender&version*:above*=4.0.0
