[jdom-interest] Possible BUG in XercesErrHandler class

[Brett McLaughlin]

Actually, I think it is best as it is. For novices, they can just trap one,
API-neutral exception (IOException). For folks like you who want more, you
can set your own error handler, giving you as much control as needed. Do you
disagree?
