After looking at the spec. again I noticed that there are two factory
methods named createSVGColor() and createSVGPaint(). There could be a
problem if SVGColor inherits from CSSValue, since these methods create
their objects outside the context of a CSS property.  This means the user
will not be able to use the CSSValue::setCssText() method since there will
be no property grammar to parse against.  Perhaps a better solution,
rather than having SVGColor inherit from CSSValue, would be to do
something like the following, which is similar to how CSSPrimitiveValue
retrieves its RGBColor, Rect and Counter objects.
	SVGCSSValue : CSSValue 			// where SVGCSSValue has a valueType of
		SVGColor getSVGColor();
