Building the Ontology Layer of the Web

The Web ontology language must be able to describe and organize knowledge in
the Web. Fine words, but what do they mean? Well, starting from the back (a very
good place to start), the Web ontology language is part of the World-Wide Web,
not just the semantic web [1]. The Web ontology language should be able to describe and organize knowledge expressed in XML, ``the universal format for structured documents and data on the Web'' (http://www.w3.org/XML/), not just knowledge expressed in Semantic Web languages, such as RDF and "RDFS".
Unfortunately, this first requirement is already problematic, as there is a
gulf between XML and RDF [3]. Will the Web ontology language work with knowledge
expressed in XML, and bypass RDF, or will it work with knowledge expressed in
RDF, and ignore XML? As there is vastly more knowledge expressed in XML than
in RDF, the answer to this should be easy - work with XML and bypass RDF.
