Please have a look at the DOM Level 2 HTML Specification[1] (not Core): In Section 1.6.1 "Property Attributes" there is stated, that a one-value Value according to the DTD (e.g. disabled) has a Object Model Data type of boolean[2]. Although it is also stated that such exposure of attributes as properties is done for backwards compatibility and that it is deprecated in favor of the generic methods on the core Element interface for setting/getting/removing attributes, e.g. getAttribute etc., my checkbox example shows that browsers do not have implented that correctly yet. Thus the time to deprecate has not yet come. Have a look at the Interface HTMLInputElement as well for example. The disabled attribute is of type boolean, as well as the checked and the readOnly attribute[3].
