If all you want to specialize is the name, then it seems to me the right
thing to do is 

(1) create

   namespace boost{               
   namespace serialization {     
   namespace stl {              
      template <class T> struct container_element_name {
         static const char* name = "item";  
         // I forget if it's legal to initialize that inline or not
      };
   }}}

(2) replace the hardcoded "item" in the library with

   container_element_name<T>::name

(3) specialize this tiny little class (rather than specializing a whole
big function/class) as desired:

   template <> container_element_name< MapTiles > {
      static const char* name = "tile";  
   };

Yes/no/maybe?
