Re: [TLS] PR#345: IANA Considerations

It looks like we have rough consensus to accept this PR. We can still have
discussion on the naming of the categories.  We will also have to define
the IANA registration policy for changing the "recommended" bit.   I'll
open an issue for this,  I think changing the bit to recommended should
require IETF consensus.

Cheers,

Joe
