gc:CodeListRef

Reference to a code list, possibly defined in an external document.

Rule: The code list reference must be valid.
An application may use the CanonicalVersionUri to select a local copy of the code list.
If there is no CanonicalVersionUri, the CanonicalUri may be used to select a local copy of the code list.
Otherwise the LocationUri value(s) may be tried in order, until a valid code list document is retrieved.
An application must signal an error to the user if it is not able to retrieve a code list document to match the code list reference.
