RE: [wsdm] URNs v. URLs for XML namespace

That is fine. If OASIS gives us a URL at which we can host proper schemas that is fine. It becomes ugly when people start making up URLs that point nowhere.

Subject: [wsdm] URNs v. URLs for XML namespace

Not that I am an expert on this, but I asked around at work and most people recommended URLs.  Here is the best write up I was pointed to:
