OK, I am replying only to the lists now.
This "Reply All" has escalated to the point where I get 5 identical
replies to my reply.

The question is: why can the exception argument passed to fataError()
wrap another exeption then?

That would negate the "cleanup" potential of endDocument.
I am not against this, as it is the normally expected behaviour
when an exception is thrown, but I would consider parser exceptions
no different from user exceptions.

So, what you are saying is:

- if fatal error, call endDocument
- if exception, do the normal thing (i.e. don't call endDocument)

I can live with that.
