Excellent!  Thanks :-)

Makes sense.  Just to be clear, are you saying that you would include 
serializer.jar in Ant's lib directory if Xalan doesn't ship with it 
included in their jar, but not include serializer.jar in Ant's lib 
directory if Xalan does include it in their jar, even though Ant 
doesn't ship Xalan?  Hmm... I might alert the Xalan team to this.  I 
suspect this might more than just an Ant-specific concern.  I'll 
report back with any information I find.
