Thanks all, for the answers!

Some serious digging later... I found some very early comments about this
issue (Mainly between Tim Bray and Dave Megginson)

that's a fair point; the correct solution per design principles
is to have a Text class that could give you a String if you
asked it; since many applications will ignore the comment of many
elements, it seems vital not to have an interface that makes
lazy evaluation impossible. So I think you have to go for either
the char[] trick or another class.

That's the best I could find for now but it should do.  I also got some
great offlist answers.  Thanks for the direction in where to start looking
Dave... Hard to believe that SAX is coming up on 4 years old at the end of
this year...
