        <#if CarrierInformation_Map["Immatriculation"]??>

        <#else>
            "registration_number":"no plate number",
        </#if>
    </#if>

        Boolean : .Bool
        Float : .Float
        Timestamp : .Timestamp.DateTime or .Timestamp.AuthorTimeZone
        Int : .Int
        String : .String
