The critical part of the analogy is with the operations on the data
(e.g., add, subtract, multiply, divide).  For both math and logic,
the operations are defined in terms of the syntax.  That's important
for both human understanding and computer efficiency.    (03)

Since Ed agrees with me, I agree with him.  Amazon.com, for example,
uses an XML representation for messages to suppliers and partners.
But their DB itself is relational.  And their XML encoding is more
compact and readable than if they had used RDF/XML.    (05)

Yes.  That's what Ed said.    (07)

We all agree that sound models are critical.  The use of XML for those
models is *independent* of how RDF and OWL are represented.    (09)
