depending on whether you want your container to always be serialized 
this way, or just for your specific file type, you could derive from 
xml_oarchive and implement a save_override function - see the Archive 
concept documentation, or you could implement a serialize() function for 
your specific container or the type holding the container.

the latter case would either look like
---
void serialize(Archive &ar,std::map<my_key,my_val> &,unsigned int)...
or
---
struct container_holder{
   //Serializable
private:
   std::map<my_key,my_val> container;
};
