I have for example this modification of PortalContent:

## added for ZPatterns
from Products.ZPatterns.DataSkins import DataSkin

## changed for ZPatterns
class PortalContent(DataSkin, DynamicType, SimpleItem):
    """
        Base class for portal objects.
  """
.....

so I need to completely replace the 
Products.CMFCore.PortalContent.PortalContent
with a new class defined (mainly copied from original)
 in the __init__ of the Patch?

can I do this with:
--
import Products.CMFCore.PortalContent

<<define myclass here >>

InitializeClass(<<myclass>>)
Products.CMFCore.PortalContent.PortalContent = <<myclass>>
--

Is it the same to replace a class  in a module than replacing 
a method/attribute in a Class ??

thanks
