Yes.

Actually, there is a buglet in XMLDocument that was made effective
by a fix to a bug in Acquisition.  Prior to 2.1.5, there were cases
where acquisition-wrapped objects sometimes didn't have their full
acquisition context.  This was fixed in 2.1.5.  Unfortunately, 
some applications may depend on the old incomplete wrapping. :(

In 2.1.5, when you add an XML document, you get a
WrongDocumentException.  This can be fixed by changing:

        if document and ownerDocument and document != ownerDocument:

to:

        if (document and ownerDocument and
            getattr(document,      'aq_base', document) is not
            getattr(ownerDocument, 'aq_base', ownerDocument)
            ):

in the appendChild method in class Node in file Node.py.

There may be other problems, however, I'm not very familiar 
with XMLDocument and wouldn't be a good person to find them.

Perhaps you could apply this patch and see if you can find 
anything else wrong.  If you do, please provide me and Amos 
with some sample data and instructions for reproducing the problem.
