Come on Tom, CSS is already compatible with lots more software than a
new tag will probably ever be. Besides, my point (answering to Frank
Manola's suggestion) was that, as things are today, we really don't need
a new tag; we have a wide variety of options bringing confusion already.
Two more points you may have missed in reading my post in a hurry:

  1) XHTML wants separation of content and presentation information; it
dictates CSS as a medium for rendering directions.
  2) You can also put your RDF somewhere in the head section of the
document; it will not be displayed by html aware browsers.

Also, RDF data like DCMI can easily be transformed to <meta> elements
[1], although I personally dislike the idea. For *embedded* RDF metadata
I would prefer XHTML m12n in XML Schema [2] (no flames please ;-). The
zip at [3] provides a really good and easy to modify schema for related

IMHO, external metadata provide more benefits; modularization always
makes things more tidy and flexible. A <link rel="meta">  element is
more than good enough for me right now and does not break validation
