Dear XOM developers, dear Saxon developers,

sorry for crossposting, but this bug is actually related to both XOM
and Saxon. As far as I can judge on that, Saxon generates DOM output that
is not completely valid and makes XOM's DOMConverter crash.

I'll need to think about this one. However a elf-contained test case
would be very helpful in figuring out exactly what's going on and whose
problem it is.

Please see the attached files. In order to run them, make sure that XOM and Saxon and the current directory are in the classpath, e.g.

Thanks for the test case. The problem is a common bug in DOM code. Specifically you never made the DOM factory namespace aware. After

DocumentBuilderFactory df = DocumentBuilderFactory.newInstance();

You have to add

df.setNamespaceAware(true);

That this isn't the default--that non-namespacewareness is even allowed--is just one more example of DOM brain damage.
