This problem report is much better than the last one.
But, it is still not optimal. You do not tell, what does not 
work, what exceptions you get (with traceback) if any.

I expect, you get an "AttributeError" for "default_css".
This is because (almost surely) "container" is the product
and not the ZClass but you said above the DTMLDocuments to
be copied where inside the ZClass.
By the way, you must be very precise when you report problems.
What is where and should go where is crucial for any useful
response.

When the objects to be copied are indeed inside the ZClass,
it is easiest to access them via the instance (accessing
them via the ZClass is very difficult).
You can use "manage_clone" (from "OFS.CopySupport.CopyContainer)
to do the copying.
