* AtRuleCSSStyleDeclaration is a subclass of CSSStyleDeclaration that is used
* specifically for the .style attribute of the JavaScript FontFace object.
* Since @rule related objects use AtRuleDescriptorID instead of CSSProperty or
* CSSPropertyID, it's convenient to use a separate CSSStyleDeclaration
* subclass.
* Spec here:
