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.

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.
