Hello Tom,
I tried using the native API too but ran into the same problem when a
DOMImpl is created from my DOMSource. (NullPointerException at
endDocument).
Kind regards,
Steffen

Hi,
The XSLTC engineers who worked on the TrAX implementation
are on vacation, so it will be a while before they can help.
The TrAX implementation for XSLTC is not fully debugged.
That may account for the problems you are having.
Since you expressed an interest in performance, you may
be better off using the native XSLTC API. See
http://xml.apache.org/xalan-j/xsltc_usage.html#native_api
It has undergone a lot of testing and is in pretty good shape.
