What's happening when you move a document? Isn't the document still the
same? If so isn't it describing the same target?
Even without moving the document, the RDDL description for RDDL is
located at http://www.openhealth.org/RDDL/ . Is it describing
http://www.rddl.org/ or http://www.openhealth.org/RDDL/ ?
I think that the whole system would be more robust and easy to use if
the target was explicitely mentioned.

I have re-read the introduction and I see what you mean. It meets the
requirement "what's behind a namespace URI?", but doesn't meet the
common usage of resources discovery on the web: if I find a web page by
any mean I like to be able to tell what this page is about.
When I find a RDDL document, I need to be a human being to have a chance
to tell what that's about, it's very frustrating for web crawlers like
the one I intend to present at XML Europe 2002 :) !
