Re: [lamps] [smime] [Editorial Errata Reported] RFC3394 (6942)

I just compared this to NIST SP 800-38F, and it looks to me like this mistake has been in the document unnoticed for a very long time.  The algorithm description in Section 2.2 seems to be correct, but the notation description in Section 2.1 has an error.

Can someone else take a look?  Obviously, by coauthor cannot help any longer...
