This is the same type as what is spec'd. We cannot use a URL record for this member as the spec in some scenarios will set and compare the URL string to an invalid URL value, such as the empty string. With implicit string constructors for the URL class removed explicitly using URL::Parser::basic_parse makes the code look quite silly in those places.
