Michael Glavassevich commented on XERCESJ-589:
----------------------------------------------
Setting aside that this would probably be far more work than just fixing the
problem in the current implementation (and more risky; likely to introduce more
bugs given the size of the change) we cannot do this either. Even with Sun's
move to open source, we cannot bring their GPL'd code into Xerces (or any
Apache project for that matter). See Apache's third-party licensing policy
here: http://people.apache.org/~cliffs/3party.html for more info.
