[faq] why do so many widgets have no @valuenow set?

Al Gilman (with some modification to the FAQ in the first paragraph):
>
>
> the @valuenow attribute is used to hold a number for
> widgets, such as sliders or a progress-bar, where the value of the widget
> is discrete.
>
> Where the state of the widget is directly visible in
> child content, that is all that is needed and that
> is where the API binding gets the value for the
> accessible objects.
>
> Q: is that the way to answer this?
