Hi Orie,

If you are willing to share your impression about the discussion that would be 
great.

However, I would not only focus on the question about algorithm identifier.
There is also the topic about encoding of what is produced by the KEM. We had a 
heated discussion about it as well. I am still unhappy with how it went.

Ciao
Hannes

I agree.

It might be helpful to have a recap of the topic, so that any new attendees can 
see the arguments presented.

With the chair's approval, I'm happy to send a *short* recap to the list of my 
views on the topic.

Hi Hannes,
dear chairs,

I concur that we have to resolve the effective blocker highlighted by
Hannes and would like to add a request of agenda time to discuss the
results of the consensus building procedure.

Viele Grüße,

Henk
