Um, XML is "a dialect of SGML" - it is not all of SGML.  It still seems
to me that many of the key benefits of SGML do require a DTD.  On the
other hand, DTDs *are* reasonably compact and they are eminently
sharable, so I don't really see the need for a DTD as a problem.

I still expect a future that includes good, widely-used SGML browsers
and a number of DTDs that are used for large parts of the
content-oriented material on the Web.  For instance, I expect that the
DocBook DTD would be used by a lot of authors, once effective access to
DocBook tagged material was commonly available in browsers.

Most authors are *not* going to have any interest in designing their own
DTDs, but many are going to want to use DTDs much richer than HTML and
with large enough user communities to support publishing of author aids
and training materials.

It's still the case that standard DTDs are required if we are to get the
best use out of indexing/search systems, since the best searching
requires some awareness of the semantics of the data, which means the
indexer or the search engine must know something about the "meaning" of
the tags it finds.
