Yes, I agree with you. But that means we still need a way to find out 
whether the input XML has changed. Because only if it hasn't changed, we 
should use the monitoring system.

And since we don't know whether the input XML is a file or a stream or 
something else, we need a very generic mechanism to monitor it.

My suggestion with monitoring static tags is meant for exactly that 
problem. It is a little overkill and I'd prefer something simpler, but 
currently I have no other idea how to monitor the input XML.

Ulrich
