If anyone wants the xml2rfc source for RFC-5581, just let me know.  You can make almost any "add this cipher algorithm to OpenPGP" draft with very little more than cut and paste on top of that.  Of course, that's just gives you a draft document.  There are quite a few more steps in producing a RFC.
