 Form control.
 Note: Depending upon the environment in which the page is being viewed, the value 
 property may be read-only for the file upload input type. For the "password" input

All Document Modes (All Versions)

Setting the type attribute of the HTMLInputElement interface to an invalid value throws a JScript Error object with a description of "Invalid argument" and an error number of  0x80070057 (-2147024809).

C0016:

The specification states:

 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. Note: During the 
 handling of a click event on an input element with a type attribute that has the 
 value "radio" or "checkbox", some implementations may change the value of this 
 property before the event is being dispatched in the document. If the default 
 action of the event is canceled, the value of the property may be changed back to 
 its original value. This means that the value of this property during the handling 
 of click events is implementation dependent.

All Document Modes (All Versions)

If the default action of the click event is canceled, the value of the checked attribute of the HTMLInputElement interface is changed back to its original value.

The value of the checked attribute of the HTMLInputElement interface changes before a click event is dispatched.
