Strongly agreed with Ian here.

There has been a trend towards many folks in W3C making claims like
"Everything is metadata" because they have tricked themselves into thinking
so, and it is a convenient rationalization for RDF.

The reality is that most of what these folks call "metadata" is called
"content" by people that actually produce web pages.

Agreed again.  In fact, such case studies of real world semantic HTML being
published on the web would likely form a great requirements document for
additional XHTML M12N modules.  I have yet to see such a case study.

This reasoning has been proven false time and time again, since there are
many specs that came out a while ago that browsers ignored, and yet some of
these same browsers are implementing newer specs.

And unless you are a browser implementer, you are in no position to assume
what implementers will or will not implement; such statements are purely
pessimistic speculation that doesn't serve any productive purpose.

The problem is one of data.  To properly design additional sets of tags to
add to HTML (XHTML M12N modules), there needs to be a good study of what
semantic authors are doing today.  And just sending out a survey won't get
you the right information either -- you'll get responses indicating what
people *think* they want, rather than what they'll actually use.  Looking at
de facto class names is a much better indicator of what new semantics
authors are actually *using* today.
