    Set a multiple weapon classes id by notetag: <classes id: id, id, id, ... >
    Ex: <classes id: 1, 3, 5, 8>

    Set a required weapon class to enable Armor / Accessories being equipped
    by notetag: <req wpn class: number>
    Ex: <req wpn class: 1>

    So, the armor / accessories can only be equipped if an equipped weapon has
    the class id which is configured in armor / accessories notetag.
