MSIR.0860 Can't extend (classtype)
The indicated class type (enumeration, file/group class, collection) cannot be extended. These somewhat arbitrary restrictions might be lifted some day, but for now they must be coded around. One way of working around the restriction is to contain a reference to an object of the class that is not allowed to be extended. Quite often this is as good (or even better!) than extending the class.
