Ok, that's clear now.

Whats still really puzzling me is this question:

The addform directive is creating the addform by using several macros
and fill the slots in the macros. How do I know which macros
and slots it is attempting to use?
For example: I want to create a customize a containerView. How do I know 
which macros it uses and which slots it fills?

Thanks,
Florian
