I went with the DOMFormatter because the XMLCContext was giving me 
grief when reloading my webapp in Tomcat.  I'm running Tomcat from 
within JBoss.  For some reason it is not noticing changes to my servlet 
so I have to touch web.xml.  This redeploys the servlet, but something 
happens to the context because from that point on 
XMLCContext.getContext(this) will return null.  To get around this I 
have to restart Tomcat/JBoss.
  The DOMFormatter does not suffer from this problem so I'm using it 
for now.  Only thing is that I've made use of OutputOptions and I still 
see no change in the source output.

                try{
                        response.setContentType("text/html");
                        OutputOptions output = new OutputOptions();
                        output.setPrettyPrinting(true);
                        output.setFormat(OutputOptions.FORMAT_HTML);
                        output.setIndentSize(2);
                        DOMFormatter df = new DOMFormatter();
                        df.setOutputOptions(output);
                        ServletOutputStream sos = response.getOutputStream();
                        df.write(page, sos);
                }catch(IOException izzy){
                        izzy.printStackTrace();
                }

Anything else I need to do to get it formatted?
