Sean,

I agree with that in general. Just as we've tried to get style information
out of the document and into a separate stylesheet, so we should get
metadata out of the document and into a separate document---which is the
point of XPackage: to use metadata externally to link various resources
(HTML, stylesheets, namespaces) together.

Really, then, RDDL is just a bunch of metadata telling how namespaces
relate to stylesheets, DTDs, etc.---in effect, it's an XPackage document
that uses XLink. What Tim and others are saying is that they want a browser
to be able to see the metadata, which is why they propose XLink XHTML. This
is where the response comes, "OK, then, just put your RDF, be it XPackage
or whatever, in an XHTML document."

The *best* solution, of course, would be to 1) use RDF to encode RDDL-like
information, and 2) get browsers to automatically display RDF, just like
they display HTML. (Displaying RDF is *much* easier than rendering HTML,
anyway.) The information would be encoded in a semantically robust manner,
and everyone would be able to see it.

Perhaps putting RDF inside HTML is really just a hack that will allow us to
wait until major browsers allow RDF viewing. I agree---in a perfect world,
the metadata should go outside the document.

P.S. Maybe IE and Netscape could just go ahead and support RDF browsing,
and we would all be happy.
