Given the time, other commitments, and closeness to the
deadline, I put something there that would clearly indicate a
direction without taking the time to check 5226 or laying out a
table that would have made the intent more clear.  That
represented a tradeoff between having an updated document the WG
could discuss in Quebec if it were so inclined and missing the
posting deadline.   I probably should have inserted a note in
the draft indicating awareness of those issues but didn't think
to do so.  Sorry.  Addressed in the next draft.

While I understand your concern, we create registries in
protocol specs fairly frequently.   In retrospect, we should
have make explicit provision in RFC 5797 for registry tables
("subregistries" if you will) for argument values to base FTP
commands as they are extended.   It seems to me that creating a
separate document either to create this particular registry or
to establish the general principle would be mostly a waste of
time.  YMMD, but that is how I intend to proceed until / unless
the WG tells me otherwise.

Again, thanks for the close reading.
