Character events do not usually have their boundaries where
you would want to create a string object from. It makes therefore
sense even today to leave that API as designed. Just create a helper
class that accumulates characters from sussessive events and
allows you to turn them into a string when an appropriate boundary
(like an end of element tag) is reached.
Aside from that argument, let's just say that if there was no "low level"
XML API one would have to invent it.
