description: This extension is used to indicate whether the medication can be substituted for this patient, i.e. whether it is allowed.                          (For a prescription, MedicationRequest.substitution is used to record whether a substitution is allowed or not.                          When dispensing, a performed substitution is recorded in MedicationDispense.substitution.)
