My best brainstorm is to move JDOMFactory and DefaultJDOMFactory into
org.jdom. It's arguably appropriate, since they can build document
components anytime, not only during the input phase. We add a
NonVerifyingJDOMFactory which uses package-protected constructors to
build objects without verification. Parsers use that factory by
default. It builds the same classes as always, but skips the Verifier
calls. Other people who know what they're doing can use the factory
also, but they'll be the experts knowing what they're doing.
