I'd actually tried the authors, but no reply yet (only a few days). I also tried the RFC Editor thinking they might have e.g. XML from which extraction might have been easier, but also no response yet. And I had found several libraries, but not the RFC code. I can't see any suggestion that the library you indicate includes that code, it also bills itself as a C++ library, which the RFC code is not (and also not what I want, but that's not a subject for this list). But the broader point is that if it's worth the IETF publishing the code as an RFC, it's worth making the code available straightforwardly. For me, a thanks to Tony Hansen, who did the extraction for me. (That makes me feel a little guilty, why should he do my work I could have done?) But the point of posting on this list was to say that the code should be available so that each person wanting that code doesn't have to do that again.
