Simon, I'd be pleased to see you expand on why it's unfortunate.
Several possibilities occur to me, but it would be interesting to know
which, if any, of them you are thinking about.
I think an argument could be made in the other direction, too -- that
HTML, or any other notation, should be regarded in whatever way its
authors regarded it, because that's an attitude that's fundamentally
necessary for communication between human beings to succeed.
I usually treat HTML as slightly-defective SGML; it's an attitude that
works pretty well for me.
