The "subdivide into iterations" part is left as a FIXME for now, until we have a way of knowing if a property is a list or not. The parse_a_css_style_value() helper has an unwieldy return type because of the requirement that it return either one value or a list of values, but sticking to the spec here seems worthwhile for now.
