Well, what do you think?
We intended to allow error values to be defined in the future if someone
comes up with a reason.

The precedent in RFC 2205 is that only Error Values that are defined are
mentioned. Error Codes that have no Error Values are defined with no mention
of the Error Value. For example, Error Code 3, 4, or 6.

We could curtail this explicitly in the draft if there is demand from the
group.

Cheers,
Adrian
