Robert: right,  I don't want to do/have neither a) nor b).

The solution that Bill proposes does indeed what I need. However I wanted to 
avoid these kind of "global" flags and to know if there are
already some built solutions wihtin the library itself.

Here is my concrete case:

struct parkinglot {
    // static data
    ...
   // simulation data
    ...

    template <class Archive>
    void serialize1(Archive& ar, const unsigned int version) {
        // static data
        // ...
    }

    template <class Archive>
    void serialize2(Archive& ar, const unsigned int version) {
        // simulation data
        // ...
    }

};

I want to serialize static data indendently of the simulation data and vice 
versa.
Of course, the best solution would be a redesign of this data structure.
But the question is: does the library offer a solution to declare more than 
one form of serialization for the same type of Archive?

Thanks,
Vidal
