Then draft-dekok-emu-tls-eap-types will have to describe how TLS-based EAP types do or not do the commit with application data.

As far as I understand, 0x00 will work for these other EAP types as well, so not need to change any thing in draft-ietf-emu-eap-tls13.

Cheers,
John

      For initial authentication, TTLS requires TLVs inside of the TLS tunnel.  For resumption, the inner tunnel isn't used.
    
      So it looks like the other TLS-based EAP methods will have the same issue, when resumption is used.
