Instead of using the V3 binding names CNE and CWE, allow to specifiy all FHIR related binding types: required, extensible, preferred and example.
Adopt the schematron engine as well to
submit an error on instances containing codes not in the bound value set on binding strength required,
submit a warning on instances containing codes not in the bound value set on binding strength extensible, preferred
submit an info on instances containing codes not in the bound value set on binding strength example
