Thanks, I think I've got the idea and how to use it for my purposes
(those sets are really powerful, my respect to the developers!).

But unfortunately I don't get it to work, I hope it's only a small
mistake by me:

This works:
  access 
    to dn.regex=".*,(ou=[^,]+,ou=data)"
    by set.expand="user & ([ou=data1,ou=data]/owner)"

This does NOT work (the owner of ou=dataX,ou=data does NOT get
access to the corresponding child entries):
  access 
    to dn.regex=".*,(ou=[^,]+,ou=data)"
    by set.expand="user & ([$1]/owner)"

(Of course, the first one is not exactly the same as the second one,
because the first one allows access to ALL dataX-subtrees to the owner
of the data1-subtree...)

But why does the second one not work?
