Hi Donald,

I guess it’s up to the wg to decide if a registry is needed or not. I was just 
wondering why it was decided to not have one and wanted to double-check that 
this is the right thing to do. I’m fine with that.

I would however, recommend to add a sentence saying that a document that would 
want to use any additional value would also need to set up a registry. And 
further, while table 4.1 says "Available for assignment by IETF Review“, table 
3.1 doesn’t; i would recommend to add this there as well.

Mirja
