Interesting.  The advantages of an HTML architecture is that it is an SGML
language.  You could extend it with your own elements, or restrict it.
You could rename elements.  You can change its representation with DSSSL,
you can create new kinds of links with Hytime.  With SGML you can define
parsed and unparsed entities, etc. mix in different SGML architectures like
DSSSL (or what Math ML could be).  There would be even more possibilites
for developers of pages and still no dependencies on server sides.  All
done with ISO standards, no need to make anything new up.

But for some reason SGML is just to difficult to parse.  I don't see why
James Clark can write an SGML parser and give it away, but large companies
with hundreds of employees can't manage.
