Hm.  I can appreciate that.  I would however like to include the .jar. 
I think that Xalan people will be smart enough to pick up on it.

Also, I would like Xalan support compiled in by default.  Xalan
developers should *not* use teh <xsl> tag because this would be stupid. 
Therefore although it was linked against the old Xalan it won't be a
problem.  We should however mention this.

On including .jar files... I really don't think this is a big problem. 
I do not however like the project-x/javac stuff and I am glad that is
gone.  However xalan is OSS and our own Dog Food so we should eat it :)
