So Miles, if you prefer the occasional synchronization issue
to the routine method invocation overhead, use a parser that
obliges you.  (Yes, I'm assuming SAX2 doesn't mandate any
interning, just exposes whether or not it's done.)

Though I daresay you'll find that the synchronization isn't
usually measurable, while your evidently preferred alternative
(lots of String.equals calls) will consistently show up as a
performance problem.  At least that's been the case when I've
made such measurements.
