def METHOD_NAME(self, dict, n=0, top=1):
    # XXX:  this method is used to do some strange remapping of elements
    #       and namespaces .. someone wants to explain that code?
    # XXX:  i also dont understand why this method returns anything
    #       as the return value is never used
    # NOTE: zope calls this to change namespaces in PropPatch and Lock
    #       we dont need any fancy remapping here and simply remove
    #       the attributes in del_attr
