This weekend, Julian stumbled upon what I think is a clear error in
RFC4408.

Section 8.1. "Macro Definitions" says, in part:

   Uppercased macros expand exactly as their lowercased equivalents, and
   are then URL escaped.  URL escaping must be performed for characters
   not in the "uric" set, which is defined in [RFC3986].

Unfortunately, the "uric" part is wrong.

First, there is the minor point that the update from RFC2396 to RFC3986
deprecated <uric>, and RFC3986 only mentiones it in an appendix.

Then there is the minor point that "uric" is not a character set, but
rather a set of strings.

The major point, however, is that this never should have been "uric"
but instead it should have been "unreserved".

Ok, before I list this as an official erratum/errata/whatever, do
people agree that this is really an error in the RFC?

Since Wayne and I have worked this all out, I obviously concur.
