I'd be very grateful for examples of where substitution groups don't
enable the reconstruction of parameter entity usage a la Maler and El
Andaloussi.  I know about the multiple inheritance problem here, and
we're looking at that as a possible requirement for XML Schema 1.1,
but even here clear examples of what you can't do without that would
be helpful in arguing the case.
