disabled: Type: boolean; Indicates whether the element is disabled or not. If this element is set to true the element is disabled. Disabled elements are usually drawn with grayed-out text. If the element is disabled, it does not respond to user actions, it cannot be focused, and the command event will not fire.

focused: Type: boolean; This attribute is true if the element is focused.

preference: Type: element id; Connects the element to a corresponding preference. This attribute only has any effect when used inside a prefwindow. The value of the preference will be updated to match the value property of the element.

tabindex: Type: integer; The tab order of the element. The tab order is the order in which the focus is moved when the user presses the "tab" key. Elements with a higher tabindex are later in the tab sequence.

value: Type: string; The string attribute allows you to associate a data value with an element. It is not used for any specific purpose, but you can access it with a script for your own use.
