[Med] We are simplifying the assignment for some code points while allowing for a range to be reserved to key extensions. This is simple compared to "Standards Action" I have seen in some experimental RFCs! > > Convert Error Messages > It has a range assigned via IETF review and a range assigned via > Specification required. > Same comment as above, except more strongly - for error messages, IETF > review seems excessive to me. [Med] Why? The same considerations (interoperability) apply for the error codes and TLVs. > Also, would it be useful to have some space for Private use? [Med] Makes sense. > > Section 11 Example Socket API Changes to Support the 0-RTT Convert > Protocol > " As an example, on Linux, a client can send the 0-RTT Convert message > inside a SYN by using sendto with the MSG_FASTOPEN flag as shown in > the example below" > Is this example right?
