In your previous mail you wrote: > => I can't understand why the copyright about a text is a problem > for software when the documentation is explicitely "without > restriction of any kind". Where does it say this? Note that the quote I sent earlier was the old RFC 2026 copying condition, which I agree with you is OK. The new text is in RFC 3667, which seem murkier to me. I cannot find "without restriction" in it, for example. => RFC 3667 style for copyright statements says nearly nothing about the rights the ISOC grants to us... IMHO you're right and there is a real issue even any restriction has to be written down to exist (the only condition is to keep the original copyright). > Perhaps we don't share the meaning of "derivative works" (for me, > this can't be code itself)? If you extract, say, a C header file, or an ASN.1 schema, from an RFC into an application, I believe that may be regard as a "derivative work". => RFC 3667 7.1e seems the right answer.
