I think so.  So, you don't want to define a new interface that
extends IAttributeAnnotatable.

You should be able to define the menu item for the class.
If you can't I'd consider that a bug.  (This bug is not unlikely,
because we may not have gotten around to supporting classes
in menu-item for attriutes.)
