Right, Ted, and I don't dispute that. I don't intend to be rude, but
I doubted that the authors knew exactly what the license they had
chosen would imply in practice. The authors are presumably not
lawyers. The license text they had chosen was in direct conflict with
the explicit goal of providing "open source code". That support my
doubt. Their willingness to modify the license also support my doubt.
I believe this is a general problem. I believe many IETF contributors
want their work to be widely used. That's why they publish their work
through the IETF rather than on their own company webpage. Many
working groups rely on free implementations of the protocol to drive
adoption. Making it easy for free implementations of protocols
further the goals of several working groups. I believe most authors
would be willing to chose a liberal license if they were aware that
choosing a liberal license will help the open source implementation.
Some areas of the IETF are driven primarily by open source
implementers (think DNS).
I'm not sure educating all IETF contributors, and ask them to include
a specific license, is the most appropriate path forward. It will
lead to an multitude of licenses in documents. We already have plenty
of weird licenses around. Few use widely known licenses. I guess
that is because people don't consider the license choice as an
important or difficult choice.
Adopting a liberal license for all documents by default would solve
the problem of having a wide range of weird licenses. People who
don't consider the license issue important or difficult get one that
benefit the masses.
Some people will not like the license. They would have to pick a more
restrictive license. I believe the IETF could accept both. The IETF
could even describe a more restrictive license. The reasons for
choosing a more restrictive license could be scrutinized when deciding
to move the document forward. This is the same as for the patent
situation.

Same here. Rejecting something because a liberal license cannot be
acquired seem wasteful. Sometimes it is not necessary or even useful.

I understand that not all documents can be published under a license
that is compatible with a wide range licenses.
I'm thinking as much of Microsoft/Apple/Sun EULA's as the GPL here.
These companies appear to have the same problem as I do with license
compatibility. Sun even incorporated part of an RFC despite the
license problem.
It is not GPL-compatibility that I believe should be a litmus test, it
is compatibility with a large set of licenses used to implement IETF
protocols. If the IETF wishes to serve its community, I believe the
license chosen should make it easier for that community to implement
the documents. The IETF license should not work against the goals of
the community.
If the IETF publishes reference code, API documentation, ASN.1
schemas, header files, etc, I strongly believe that material should be
compatible with a wide range of licenses. Trying to separate code and
text is a distraction, and we have not made much progress on this
path. The simplest seem to make all of the document available under
an all-compatible license. This will also solve the problem that
Debian, FreeBSD and Sun had with regard to the license on the _text_
of RFCs. Their concerns weren't with code-like portions.
