Type: Editorial

Section: Meta-Data

Original Text
-------------
Obsoletes: 3268, 4346, 4366
Updates: 4492

Corrected Text
--------------
Updates: 4492

Notes
-----
"Obsoletes: 4366" is factually incorrect, because it is impossible to implement TLSv1.1 (rfc4346) or
TLSv1.0(rfc2246) from the TLSv1.2 spec alone. (IPv6 does not obsolete IPv4 and HTTP/1.1 does not
obsolete HTTP/1.0 either).

"Obsoletes: 4366" is factually incorrect, because some of the TLS extensions defined in rfc4366 do NOT
appear in rfc5246 (and were updated by rfc6066).  On top of that, in order to implement TLS extensions for
TLSv1.0 or TLSv1.1, rfc4366 is indispensible, because it describes the necessary changes to the TLSv1.0
& TLSv1.1 PDUs, information that would be cumbersome to extract from rfc5246 compared to simply using rfc4366.

"Obsoletes: 3268" is factually incorrect, because 3268 is the document needed to implement the AES
ciphersuites in implementations of TLS _prior_ to TLSv1.2,
such as TLSv1.0(rfc2246) and TLSv1.1(rfc4346), i.e. to add support for AES ciphersuites to an existing
implementation of TLSv1.0, one would use TLSv1.0(rfc2246) plus rfc3268, rather than TLSv1.0 plus some
undefined fragments of rfc5246.
