Yes, for 'random access' archives (think relational database buffer here) it's
possible the archive process will need additional meta-data not provided in
the base library setup (think mapping of classes to tables and attributes to
columns). And yes, I've implemented this one before as well -- it's a very
handy bit of infrastructure. I think in the past Robert has considered this
"out of scope", but in fact I believe given the current library it could now
be done by writing and archive and perhaps some enhancements to the registration.

BTW, I think the references should include a reference to this paper which
discusses many of these variations and design issues.

Of course, the modern C++ approach of this library wisely eschews inheritence
in favor of templates, but the concepts are still the same.
