Definition

A logical reference (e.g. a reference to ValueSet.url) that identifies the value set/version that identifies the set of possible coded values this coding was chosen from or constrained by.

Comment:

If this extension is used with an extensible binding, and the concept comes from outside the bound valueset, the value set SHALL be different from the bound valueset.
