Last time I looked Sun's stuff wasn't nearly as useful as you
suggest. Basically they've thrown away ParserFactory and
replaced it with something similar which (presumably) sits on
top of their J2EE config files. As far as I remember there's no
way of specifying a particular set of Parser features.

Indeed ... and that's exactly what I've done. Check out
org.xml.sax.helpers.XMLReaderImplementations (note the plural).

That's the strategy I took for the transparent SAX 1 adaptor
stuff. Not XML tho' ... too many chicken and egg problems I
fear ;-)
