This is only meant to convey that RDF is the syntactic carrier for ontology languages and other logical formalisms (and XML is in turn the syntactic carrier for RDF). I don't think it was ever meant to imply that logic-based analysis of a domain would not be needed before using RDF/RDF Schema as a notation. The picture is only a rather matter-of-fact statement about the technical infrastructure for the Semantic Web, not a deep methodological issue. I would be happy if this clarification removes "your major complaint about much of the work on the semantic web".
