Let me clear you on this empty tag means which doesn't have any body,so the following might be empty tags .Even if you have space between opening and ending tag also that will be considered as body. Here if you observe the tag is declared with a carraige return,so it doesn't be considered as an empty tag. Correct me if i am wrong.
Vijaya, I think all white space is ignored in any XML. Please check the answers (last sentence) that are included in the code block above. It says that the first auth-constraint tag is empty. [ August 04, 2008: Message edited by: Jan Sterk ]
