I disagree with CSSPageRule.style and CSSMarginRule.style having a 
different type from CSSStyleRule.style. Some properties "do not apply" 
to the page context or margin context just like the 'text-align' 
property does not apply to inline elements, that does not affect the OM.

@page and margin rules, like keyframe rules, contains "real" CSS 
properties and are much closer to style rules than eg. @font-face which 
contains descriptors that sometimes happen to have the same name as a 
property.

The 'size' property is a bit odd in that it never applies to elements, 
but as currently defined it is a property and thus should appear in 
CSSStyleDeclaration.
