That isn't the case. See http://www.w3.org/pub/WWW/TR/WD-xml-961114.html
section 3.2 DTDs are no longer required.

That is also not the case. There already *exist* products that work with
element names. Some people already *have* them. Therefore the difference is
using what you have, or buying all new software to support a silly hack.
Some software systems for working with generic markup are VERY expensive.

Wrong again. HTML *is* SGML. Therefore it is obviously possible to make
SGML-based languages that are "all style" or "part style" or "all content",
depending on your preference. Considering the gross, complex HTML code
required to do some things, I think it makes a lot of sense to make
format-oriented SGML-based languages for format-oriented sites.

This is *not* an accurate paraphrase of my paragraph above which does not
mention validation at all. Let me say it again. It is useful to use SGML in
situations where you *never* intend to validate *anything.* Usually,
however, once people move to SGML they figure they might as well take
advantage of all of its features, instead of half of them. That will
probably change if it becomes the lingua franca of the Web.
