I don't think this is valid. The "checked" HTML attribute and the "checked" DOM 
attribute aren't the same thing. The first represents the initial state of the 
control. The second represents the current state.

If you want to toggle the control's checked state, you want to use the DOM 
attribute, as in:

    myElement.checked = true;

Maybe I'm confused, but shouldn't the browser render the current state of the DOM?

Comment 4

[Hixie (not reading bugmail)]

It does. The DOM contains a "checked" DOM attribute as well as the HTML 
attribute. The former is the visible state, the latter is the original state, 
and what resetting the form would change the checkbox to. (Otherwise, how does 
the browser know how to reset the form?)

I'm not sure though, hence my waiting for someone else to decide.

jst, this one is your call...  This is just like the "value" thing, basically,
and DOM HTML says:

checked of type boolean
    When the type attribute of the element has the value "radio" or "checkbox",
    this represents the current state of the form control, in an interactive user
    agent. Changes to this attribute change the state of the form control, but do
    not change the value of the HTML checked attribute of the INPUT element.

so the property and attribute are in fact pretty decoupled in the DOM....

This is invalid, per comment 4 and comment 5.
