It's not so much that I object to doing it on the factory, as that
the XMLReaderFactory has no
setFeature/setProperty/getFeature/getProperty methods. THerefore it's
not possible within SAX as currently designed. Perhaps we should add
these methods to XMLReaderFactory. However, that's a bigger change
that should be considered on its own merits, with a range of use
cases, rather than being shoe-horned in to support this one need. I
doubt that could be reasonably pulled off in Norm's time frame.
I suspect Norm was thinking of adding this to SAXParserFactory, a
hideous, evil monstrosity of a class that should be hung, shot,
beheaded, drawn and quartered, burned at the stake, buried in
unconsecrated ground, dug up, cremated, and the ashes tossed in the
Tiber while the complete cast of Wicked sings "Ding dong, the witch
is dead." Excuse me, I got a little off topic there. I've just spent
way too much time explaining to users that their code doesn't work
precisely because they used SAXParserFactory instead of
XMLReaderFactory, and then having them refuse to believe me because
Sun is telling them something to use SAXParserFactory.
Anyway, within SAX2 there's no such thing as factory level features
and properties. Perhaps we should add this. Unlike a lot of the
things being proposed for this minor update, this would be an API
level change, so it should probably wait till 2.1.
