Look out Excel! Edward Tufte, David Carson: >behold your new working quarters!</sarcasm> Sectioning and layout are somewhat different than text level style IMHO, for instance, the most common abuse of tables on the web is to produce columnar format (not for floats!) and it is difficult to see how this could be done effectively in CSS or something similar. Tags that divide the document into sensible parts for layout (and for the application of style) are better left in HTML; if we take *everything* out of HTML, then we are stuck supporting 2 very difficult languages for even small devices like cell phones (HTML+CSS). We need to balance the need for seperation with the need for simplicity. >But supposing I were to agree with you that HTML has a place in the >formatting equation: I think you've got it backwards.

I agree that all text-level formatting should be removed from HTML (eg <B> etc). I said this in my paper presented at the conference; http://www.cnet.com/Papers/W3C/kungpao.html. But we can't leave layout up to the browser vendors: this is what we are doing now, and it is a total disaster - not even a simple DIV acts the same in both. Should these things be independent of tag boundaries? I don't think so. This does not allow us to support intelligent internal organization of the document. >People are going to keep using "anything goes" HTML for display purposes >for a long time.

It isn't cost effective, it is difficult to learn, can't be checked, and only works haphazardly...even the, in your own words, 'least-broken implementation', is pretty bad. Moving all the problems to CSS from HTML doesn't solve anything. >What is worth trying to create, IMO, is a markup language for >general-purpose structured hypertext.

Um...this is more or less the path I proposed here, with some solutions that attempt to fix the problems you mention, which are indeed hacks and result in rapid hair loss for those poor souls who hand author their code (like nearly everyone who writes HTML). I'm not sure of the use of the term 'profile' here, I think you mean to use it in the loose sense. (In the technical terminology, HTML is an SGML 'application' not a 'profile' - an important distinction. I proposed in a previous email that it be made a profile - of XML.) Does any user agent actually pay any attention at all to DOCTYPE? HTML should be generated only by machinery, for machinery. Humans have no business writing HTML. Regards, D-
