In fact, I think Alex was referring to ZClass security, which isn't
covered in the book, and is something I've never go to the bottom of either.
on the 'define permissions' tab, it says:

   The table below has two columns. The first column lists the 
   permissions for this object. The second column specifies the
   permissions that should have this permission in this product 
   or ZClass. 

I'm probably being intellectually lazy or something, but that doesn't
make any sense to me at all.
