Certainly an "http:" URI can identify a namespace, most namespace names in
common usage are http: prefixed. 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.
