FCOL, does this have to be so difficult? Are you sure you want to
call the recommendation I'm suggesting for conforming compilers ugly?
Let me remind you, that was:

  The best thing you could do, IMO, is write a recommendation that
  works on conforming compilers, e.g.

    Overload serialize in the namespace of your class.

Are you planning to replace it with anything? It would be pretty
silly to have a section called Archive Concept with no concept

I don't really care deeply about this one, FWIW.

That seems extreme to me. Surely for RC_1_33_0 a documentation fix
that provides instructions that are both correct for conforming
compilers and consistent with the current library implementation is
possible? Not much more than a small tweak in emphasis would be

Understandable; that will take some considerable time to analyze.
