The empty string is not a valid media specifier according to the syntax definition in the specification, so I agree with you there. However, the discrepancy between "" and "," does not feel right. I don't think you can have it both ways - you'd have to modify the syntax for media_query_list to permit an empty string for the whole media query and define it as being an alias for "all". Did you ever resolve the "not foo" issue? The issue being whether unknown media types are always false, regardless of the 'not', or whether this case it true because the not always negates the result of evaluating the rest of the query. -- Stewart Brodie Software Engineer ANT Software Limited
