Oh, one other thing, the errata page says near the top:
"approved fixes"

Given that (to my knowledge) no one is currently chartered to approve 
any fixes, this could lead to the state where no errata are possible.
Or perhaps, in the absence of a WG, it's part of your job to approve 
fixes (this part of the process is not clear to me), in which case the 
page in its current state is accurate.

I thought DanBri's comment
This is a draft errata note, for review. ----danbri
was appropriate and helpful, and a similar comment would more accurately 
reflect the status of the latest erratum.
