That is equivalent to what I had written above.

Thank you!  Thus CSS is orthogonal to markup.  That is what I have been
saying all along, even though Ian Hickson disagreed with that as quoted above.

And XBL allows one to extend markup with new tags.  Yet XBL also combines
CSS and DOM dependencies in its syntax.  So I hope you understand that XBL
will make CSS and DOM dependent on markup.

Noted.  Nevertheless thanks for seeing part of my point regarding the
importance of separation (orthogonality) between CSS and markup, even if
you may or may not agree with my conclusion that XBL voilates this separation.
