Yes, that is a feature of XHTML (but not "the point", imo).  Users
don't need to obtain new browsers to view XHTML.

*grin* Does it sound that bad to you?  There will be many different
document types, yes.  But that won't hurt interoperability.  Anyone
who creates a new document type will provide a means to view it (an
XSL stylesheet is fine) and a DTD to validate instances against (if
necessary).

That's not the case at all.

You can use XHTML without a DTD.  This gives you more flexibility.
http://www.w3.org/TR/html/#well-formed

XHTML 1.1 will provide a framework for extending XHTML.  You can build
an XHTML module with your own tags.  Then, if you like, you can
generate a DTD that includes basic XHTML and all your extensions.
http://www.w3.org/TR/xhtml-building

If that's not "open" enough, you have other alternatives.  Make up
your own XML document type.

I don't understand what you've written here.  You seem to have a mental
model of how the web should work, and that an XHTML DTD runs counter to
that... but I hesitate to interpret your statements; I don't know
precisely what you mean.

Right, this is the real issue.

The intent of W3C Recommendations is to help the Web grow and improve.
This means value judgements are involved.  The W3C should not
recommend features that hinder security, interoperability, or
usability on the Web.

The extensibility is still there, but the W3C will try to avoid
recommending poorly designed extensions.
