[css3-2d-transforms] DOM interfaces, especially CSSTransformValue

1)
Section 7 of the CSS 2D Transforms draft specifies a number of DOM  
interfaces, among them CSSTransformValue which inherits from CSSValueList.  
However, according to an earlier message from the WG [1], interfaces  
inheriting from and related to CSSValue are "classified as obsolete", and  
"[i]mplementors are strongly urged not to implement them". This would seem  
to apply to CSSTransformValue and probably also CSSMatrix as written.

2)
It seems inconsistent/confusing that "getComputedStyle([...]).transform"  
would return a CSSValue, since it looks just like the DOM attributes in  
CSS2Properties which are all of type DOMString and equivalent to calling  
getPropertyValue.
