If we add a feature, they can (while parsing) say, "I > don't know what that is, but I sure know how to ignore it." That's one it's a subset of SGML - it's an application that lets you add tags. Not the first one, but the one that's gotten the most press. In theory, you could add tags in HTML that would be safely ignored by other browsers. In practice, the people writing the popular browsers did a lousy job of defining tags that wouldn't cause problems if you ignored them. Hence was born attribute-based styling and CSS. <mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
