DOMSource vs. StreamSource in Xalan

[Kenneth Partlow <kp...@cysive.com>]

I'm having problems doing a transform with a DOMSource.
I'm using Xalan 2.1.0 and Xerces 1.4.

classpath=%lib%\xerces.jar;%lib%\xalan.jar for the test.

Below is my test file.  it is relatively small.

My DOM test vs. the Stream test gives very different results, though
Stream test gives the expected results.

If I'm doing something wrong, please let me know.
