Jorge,

just checking that I understand correctly:

- a change to what rights the author gives to the IETF can't be made 
retroactively by the IETF alone.
- a change to what the IETF gives to others (provided it has the rights
to 
give) can be made by the IETF alone, no matter what the age of the
document
- any change the author and the IETF agree to is OK

Right?
