By that measure we should never have switched from SGML
when XML was introduced (for documents), or never
have switched from HTML (for pages), or never have
switched to markup languages instead of Flash.  If we
were programmers we never should have been taught
Java when C++ was around (but we would never have
learned C++ because of COBOL) ;-)

Presumably the guy has some particular educational goals
and he has found RELAX NG more straightforward
to use to teach with than XSD (=WSX).  For example, he may
have decided he does not want to burden students with
discussion of ambiguity (or, more likely, he does not
want to burden the tutors in labs from having to 
diagnose, explain and repair ambiguity errors.)

I do not believe that suitability for undergraduate classes
was ever a goal or requirement for WSX (=XSD). It was
made as an industrial language with one set of tradeoffs.

By contrast, RELAX NG was developed with limited
scope as one of its designs goals, so I would hope that
it would be more suited for the undergrads, poor shiny-eyed
darlings that they are.
