I'm not sure I follow exactly what you'd want in runtimeStyle or
currentStyle (or what the difference is).

However, I'd note that there may be value in two different forms of
specified style:

 * a CSSStyleDeclaration that has all properties specified in author
   style sheets

 * a CSSStyleDeclaration that has all properties specified at all
   levels of the cascade

I think the first of these would be preferable for editing-type
tasks (manipulating markup intended to be used later).  The second
would be a little more like getComputedStyle.

In both cases, it would have no value for properties that aren't
specified.  (This is different from computed style, which always has
a value.)


(Something else that might be interesting, although I'm not sure if
it would be particularly useful for Web authors, is a way of getting
all the author style rules that match an element.  The DOM Inspector
extension to Firefox shows this information; I'm not sure if it
would be useful from script.)
