Mmm. But that would not limit the permissions, so person could cut an 
object and paste it somewhere else etc. I decided to go with the 
manage_beforeDelete.

Below is what I added to my content-type:
-----------------------------------------

from AccessControl import ClassSecurityInfo
from OFS.ObjectManager import BeforeDeleteException

     security = ClassSecurityInfo()
     security.declarePrivate('manage_beforeDelete')

     def manage_beforeDelete(self, item, container):
           membership = getToolByName( self, 'portal_membership' )
           user=membership.getAuthenticatedMember()
           roles = user.getRolesInContext(item)
           wftool = getToolByName( self, 'portal_workflow' )
           state = wftool.getInfoFor( self, 'review_state' )
           if state == 'published':
                      raise BeforeDeleteException, 'Cant delete a 
published item' + user.getUserName() + str(roles) + str(self)
           BaseTemplate.manage_beforeDelete( self, item, container )


Hope this helps others.
