I just ran into this right now, and i'm really disappointed.
That private ::Header thing doesn't event allow any workaround.
Can't it be fixed using a version conditional call to a new virtual
Create() method at Tag() level ?
What prevented to fix -documentation- instead of letting people loosing
their time implementing Factories & Frames ?
