Sorry for spamming but one more update (after reading draft-ietf-tokbind-https):
In sec 3: "This message  MUST be sent in the client's first application
protocol message." Why is that a generic requirement for all uses of token
binding and not just for HTTPS?

Update (after reading draft-ietf-tokbind-negotiation): Given different
negotiation mechanisms could be used, maybe it would make sense to say slightly
more about version handling in this doc as well, e.g. at least
explaining/requiring that version negotiation is done by the negotiation

Maybe I'm just missing something but given the TokenBindingType and the
TB_ExtensionType share the same number space, how do I know if there is another
TokenBinding or and an TB_Extension following after the signature?

Please spell out TPM (in sec 1).
