Good point. I think that for large SGML datasets it was taken for granted that you might have
to do something to the data before it was really usable for your purposes. With XML's tendency
toward smaller and more agile datasets though, this is an unacceptable cost. I like the idea
of XML being (among many other things) the ultimate normalisation of SGML data.
