[Zope] ZClass Subobjects in ZClass instances managed through ZMI

[Milos Prudek]

Hi,

When ObjectManager is added as a Base Class when creating ZClass, the
new ZClass has a "Subobjects" tab.

If Image, Folder, or other "stock" object types are added to the
"Subobjects" list, they are then offered in ZMI for each instance of the
ZClass.

But if other defined ZClasses are added to the "Subobjects" list of the
ZClass, they are NOT  offered in ZMI.

Is that intentional?

Can I change this behaviour?
