It is not odd. When the keyword "tagged" is only inside the private section
then the "tag is hidden". Only child packages can see the tag and can
extend the class.

Remember, you can split the type into two parts: A partial public
specification and a full private specification.

The partial pubic and full private specification can inherit from different
classes of the same class hirachie.
