I think also that it is not so important to change the format during 
runtime. It is a nice to have feature but at least for me not a must.
If you can configure the output format it has one big advantage: you can 
change the format of older products without recompiling the program.
The most important thing for me that it does not cost a lot of time to 
format the message.
