A User agent with no CSS support will be very restricted. Because important styling features (like color) can only be applied through CSS such an agent will not be suitable for a lot of caption services. Especially color and background color should actually be a core feature of WebVTT because they are used in a lot of countries for speaker identification. Until these are not WebVTT features there should be a note for this new conformance class that such a user agent may not meet the accessibility guidelines in some regions/countries."}}
