Are you using DOMBuilder or SAXBuilder?  JDOM never adds a DocType
unless you truly have one, but DOM sometimes does so if you build from
DOM you might get one.  SAXBuilder is the right choice for building from
files, as the javadocs say.

Whitespace in the prolog isn't reported by SAX (due to the fact it's
semantically unimportant), so JDOM has to guess.  The latest code in CVS
is a bit better at guessing I believe than beta6.  Might want to try
it.  There was a patch sent in recently for another tweak to the
guessing logic to make it better still.
