Thank you for your answer.
Yes, we use the DominoWiki in a way, it wasn't designed for. But it's a great database for things like documentation, manuals, etc. and we can use it this way in our WebSphere Portal without the need to implement a nice web frontend (like you would do, when you use Office LiIbrary, etc.).
I will write a feature request.
