[mpiwg-persistence] Unused persistent collectives info keys in Annex

[schulzm at in.tum.de]

Hi Tony, all,

I hope I fully followed this :)

Doing an errata item seems a bit backwards to me, as we haven’t published the standard, yet. Also, removing it and then re-adding it with 83 seems odd. What about just removing the two keys that are not needed with 83 through the no/no process? Wouldn’t that be all that is needed?

Looking at the info keys, I found that there are info keys in Annex A.1.5 that stem from the persistent collectives chapter but the text mentioning them was commented out there (git blame mentions you as the last author of that part). It seems that the info keys in the annex are a relic of this text. The keys in question are:
