Remarks
This is implemented outside of CanCopy, so that subclasses can override the public CanCopy and CanMove methods independently. If subclasses want to have the same behavior for both CanCopy and CanMove, they can just override this method. (Before this method existed, overriding only CanCopy led to the side effect of changing the CanMove behavior.) The supported formats: (1) ElementGroupPrototype, and (2) custom formats
