It only took about 2 days ;-)
If my ZopeZen rises some more, I will try to add some comments on the 
HowTos about the missing or changed bits

I am using the basic Plone edit-form and would try to add my 
properties there. I did not do anything to the fields and jsut hoped 
the inherited Documtent Class would take care of it...

that it's not accurate. It seems like many things in Zope, CMF or
