I haven't checked any reference for this, but my from my experience,
the method Element#setAttribute('value','someValue'), used internally
by Element#writeAttribute method DOES NOT UPDATE the value at all.
Instead it sets the ATTRIBUTE to the value provided. When user clicks
"Reset" button, then the attribute value is re-read and put into
Element.value property.
I use this to check if the form was modified since last save. Each
time I save the form with Ajax.Request, I also copy all
Element.value's to proper attributes. And before next save request, I
check if the values had changed, only then I submit the form.
Anyway, what I want to tell, is that the element property, and element
attribute are not always the same.
