as a general rule, the included archives only implment serialization for primitives. This permits all serializations to work with all archives. Its been a constant battle to keep these things decoupled in order to preserve this feature. serializations should be attributes of the type NOT any particular archive.
As far as I understand there is a default implementation of serialization for strong typedefs, which just serializes the underlying type.
LOL - I'm embarassed to say that off hand I don't know the answer to this!!. I used BOOST_STRONG_TYPEDEF for the special types needed for the library internals and implemented in them in the archive. BOOST_STRONG_TYPEDEF will convert to the underlying type when used in an arithmetic context and I believe that this might be enough to get serialization for free. Or maybe not. BOOST_STRONG_TYPEDEF should be considered for promotion out of the serialization library into the core of boost itself. Robert Ramey
