OK, if I use xml.xslt._4xslt, it works fine. 

However, by investigating a bit further, I've found something
interesting. We where using XSLT in a slightly different way. _4xslt does
something like this (this is much simplified code, no command line option 
processing, single stylesheet used:

-----------------8<---------------
from xml.xpath import Evaluate
from xml.xslt.Processor import Processor

def test():
    import sys
    #xml_dom = Sax2.FromXmlFile(sys.argv[1])
    processor=Processor()
    #transformation=Sax2.FromXmlFile(sys.argv[2])
    processor.appendStylesheetFile(sys.argv[2])
    result = processor.runUri(sys.argv[1],ignorePis=1)
    print(result)
if __name__ == '__main__':
    test()
-----------------8<---------------
and it works fine.

If we modify it slightly, and use appendStyleSheetNode however, things get
curious:

-----------------8<---------------
from xml.dom.ext.reader import Sax2
from xml.xpath import Evaluate
from xml.xslt.Processor import Processor

def test():
    import sys
    #xml_dom = Sax2.FromXmlFile(sys.argv[1])
    processor=Processor()
    transformation=Sax2.FromXmlFile(sys.argv[2])
    processor.appendStylesheetNode(transformation)
    result = processor.runUri(sys.argv[1],ignorePis=1)
    print result
    Print(result)

if __name__ == '__main__':
    test()
-----------------8<---------------
In this case, we get the error mentionned in my original bug. Curiouser
and curiouser, if we use DowWriter in runUri, there is no error, but the
output is very strange (&#10; and spaces everywhere). 

Now the solution is to use StripXml on the transformation, and afterwards
everything works properly. Maybe the StripXml should be in
appendStylesheetNode?

Cheers,
