Embedded classes in ROOT

Dear Rooters,

I am creating a small compiled library as a new ROOT class with its dictionary definition.
In particular, the structure should be a class with some other classes embedded into it.
If I wont to store into a TTree some data in the format of one of the embedded classes, do I need to include a ClassDef statement in *each* embedded class, or it is enough to put one in the "mother" class?

In other words, should I do like this (1)

class A : public TObject {

...

public:

    class B : public TObject {
    public:

       ...
    private:

       ...
       ClassDef(B,1)

...

private:

...

    ClassDef(A,1)
};

... or like this (2)

class A : public TObject {

...

public:

    class B : public TObject {
    public:

       ...
    private:

       ...
    };

...

private:

...

    ClassDef(A,1)
};

Thanks,
