It is adapted to be used in Norway. The profile has the following changes from AllergyIntolerance:\r\n- There are restrictions to use verificationStatus since KI is using Certainty that has similar use\r\n- Reference to patient is changes. no-basis-patient should be used.\r\n- Substance is required and should include one of: ATC, FestSubstance, FestMedication\r\n- manifestation is changed to use codingsystem 7497\r\n- the profile is extended with certanity and sourceOfInformation to support national KI standard"
