The only thing is, I'm not sure about the correct way of notifying the document about the selector change, doc->styleSelectorChanged(DeferRecalcStyle);
Should it perhaps use RecalcStyleImmediately instead?

Can you add some tests of invalid selectors?

> WebCore/css/CSSStyleRule.cpp:57
> +void CSSStyleRule::setSelectorText(const String& selectorText, ExceptionCode& /*ec*/)

We should remove the ExcpectionCode parameter (and the raises in the IDL file) since the latest spec (http://dev.w3.org/csswg/cssom/#dom-cssstylerule-selectortext) doesn't have it ever raising.

> WebCore/css/CSSStyleRule.cpp:60
> +    CSSParser p;
> +    CSSSelectorList selectorList;

There is no reason to declare these at the top of the function.

Good point. Fixed "raises" in CSSStyleRule.idl and CSSPageRule.idl

Right, was moving the code around and forgot to follow on these.
