Yes, I'm aware of what HTML 1 was (Martin Bryan explains it well [1], 
for anyone that doesn't know) and, IMO, it was a very good decision to 
formalise it as SGML.  However, as you say, the real world never caught 
on, and, sadly, probably never will (at least not in any mainstream 
browser). :-(

I assume you mean tag-soup parser? :-)  Yes, I understand the problem.

Fair enough.  I guess this is one reason why XHTML is so good ? the 
mistakes of the past with SGML/HTML won't be repeated, and progress 
won't be held up so much by buggy browsers.  it's just a pity it's not 
yet supported in IE.  I'm also starting to understand why you don't 
consider HTML an application of SGML, although I still don't like it. :-|
