[jdom-interest] XMLOutputter/SAXBuilder

[Bart Read]

You could try turning document validation off (I think you can do this) --
I'm obviously assuming that you aren't going to need to validate the
documents you're creating in your final system, but I could be mistaken.  My
thinking is that if validation is turned off then the DTD won't be referred
and so the default attributes won't be inserted (because the system doesn't
know about them).

Hope this helps.
