I am not really convinced: 1. Reporting the CDATA int does not 
hurt anybody who is not interested. 2. People also might be unhappy
if they do not know if " or ' was used as quote for attributes.

disadvantages. In the end, it's ok to me to take some extra effort if 
I want to write the "same" document back from sax2 events.
