   RE: [xml-dev] which came first: content or markup?

[ Lists Home | Date Index | Thread Index ]

And that is not a good view unless one is constraining a priori. 

You may not have been around for the early rounds of the debates 
between WYSIWYG and SGML systems.  It was claimed that WYSIWYG 
was better because it enabled free text entry.  The conflict was 
that the market that could afford the then expensive WYSIWYG 
systems needed constrained documents.   Internally, a WYSIWYG 
looks a lot like HTML (or RTF).  This gave some of the SGML 
editors their first boost.   The ones that did well also had 
a way to relax the markup constraint.  One turned it on as 
one needed it.  Because information arrived out of order 
relative to the document structure, one had to relax that 
constraint.   Validation doesn't have to be on all the time. 

If XML editors are forcing it to be on all the time, another 
history lesson was missed.  That one is mystifying because 
anyone with experience knows it.  This is the data-centric, 
database-first viewpoint fumbling the ball.  Database systems 
want schemas a priori.

A content-first view doesn't seem
very popular in the XML world at present, and I can't say I see that
changing.  Markup now seems to come first.
