This was my mistake. The proposed records I posted at [1] were missing 
the Added field.

I was on vacation at the time, and the errors escaped the one-week 
review period without being spotted (only the registration form requires 
the full two weeks), but this was still my responsibility. Probably I 
copied and pasted the records directly from the registration forms, 
which never include an Added date (see Figure 5), and forgot to add it.

I was busy last night, but Amanda Baber at IANA figured out what needed 
to be done, confirmed them with me, made the necessary changes, and 
posted a corrected Registry around 7 pm local time on a Friday night. 
This was definitely an "above and beyond" moment and I want to thank 
Amanda for her dedication and expertise in getting this done.

Actually, the spec is a bit loose here: every entry must have *exactly* 
one Added field. It would make no sense for a record to have two; I'd 
consider that a structural error.

That would be a good question for IANA, since we I don't see the updated 
Registry before it gets published. Sometimes I mock one up and compare 
it with the released version when it is published, but I didn't do that 
this time, and in any case I didn't run it through my validation tool as 
Dave (thankfully) did.
