When a SAX parser calles the characters() method in your ContentHandler, it
can break up the text node into as many pieces as it likes, calling the
method once for each piece. It looks as if Xerces is breaking the text at
entity boundaries, which is a perfectly reasonable thing to do. It's the job
of your ContentHandler to re-assemble the pieces.

There are SAX filters around that do this for you but I can't lay my hands
on one immediately (the one in Saxon does too many other things for it to be
useful to you).
