This distinction between URNs and URLs is somewhat historical. A URI is more that the mere encapsulation of URLs and URNs into a single specification: a URI prefixed with the http: scheme may be used as a name. Similarly URIs prefixed with the "urn:" scheme may be resolved. XML and XML applications see no "semantic ambiguity". The only ambiguity I see is that which is attached by humans trying to read the tea leaves. -Jonathan
