OK, I see your point and more or less agree. SGML or document-oriented XML
may be the "native" storage format for lots of industrial-strength
applications (aircraft maintenance manuals being the canonical
example) but the requirement for interchange, interoperability, and usability
by future generations of software totally dominates the design.
I guess I wouldn't want to distinguish "XML" from "a representation of
the XML Infoset" however, but that's another perma-thread.
