❔ XML deserialise different types into a single list

public class Shortcut {
    [XmlElement("Keystroke")] public List<Keystroke> KeyStrokes { get; set; }
}

public class Keystroke {
    [XmlAttribute("Keycode")] public string KeyCode { get; set; }
    [XmlAttribute("Mods")]    public string Mods { get; set; }
}
