This is not so. Resources that “tag” and “urn” URIs identify may have
representations accessible on the Web. Take, for example,
<urn:ietf:rfc:2141>. Surely one can find a representation of Internet
RFC 2141 by HTTP or by FTP.

The question, rather, is whether the scheme of a given URI implies an
algorithm for dereferencing.
