DOCBOOK-APPS: Goal and Conclusion Tags

[Stephan Wiesner <stephan@stephan-wiesner.de>]

Hi list,
I used to work with a DTD developed at my university that offers the
possibility to start each chapter with a 'goal' ('What you will learn')
and end it with a 'conclusion' ('What you learned'). This is very
important for my style of writing and many of my readers praised me for
this structuring. 
I am now translating my documents into docbook and didn't find anything
similiar to this. Which tags should I use for this?
