This is actually good, because it means it is not your files
but your setup.  8^)

If it is any comfort, I have found that Norm's stylesheets
are an excellent stress test of any XSLT processor because they
exercise so much of the spec.  Most test stylesheets just
do a few templates for sanity checking.  I even suggested that
the Xalan folks use his stylesheets as part of their
test suite.

Given your CLASSPATH, I suspect a mismatch between the
parser and Xalan.  When I run Xalan, I specifically add
xerces.jar and bsf.jar to my CLASSPATH.  In your CLASSPATH,
I think jdom is serving as your parser.  In my experience,
Xalan seems to depend on a specific version of Xerces.
My classpath is set like this in a script I use to
execute java org.apache.xalan.xslt.Process:

XALAN=/home/bobs/xalan-j_2_0_0/bin
CLASSPATH=$XALAN/xerces.jar:$XALAN/xalan.jar:$XALAN/bsf.jar

These files all come with the Xalan2 distribution.
This ensures the matching xerces parser for Xalan2.
Hope this helps.
