Xinpeng,

Option 2 is the correct one.

Hi all,
When I review HTTP2 protocol draft, I find that for the description of "Use of TLS Feature" in sectiion 9.2, there is some change from v15 to v16 as following:

In v15 it says:

"Implementations of HTTP/2 MUST support TLS 1.2 [TLS12<http://tools.ietf.org/html/draft-ietf-httpbis-http2-15#ref-TLS12>] for HTTP/2
over TLS. "
But in v16 it says:
"Implementations of HTTP/2 MUST use TLS [TLS12<http://tools.ietf.org/html/draft-ietf-httpbis-http2-16#ref-TLS12>] version 1.2 or higher
for HTTP/2 over TLS." (v16)
Maybe I have missed some discussion in the list about this, but could you someone tell me the reason why change "support" to "use"?
For the description in v16, how should I interpret the description:
Option 1: HTTP/2 MUST use TLS, and the versioin of TLS MUST be 1.2 or higher.
Option 2: If people want to use HTTP/2 over TLS, then the version of TLS MUST be 1.2 or higher.
Should I take option 1 or option 2?

it will be appreciated if some people can give some clarifications about what I mentioned here. Thanks!

Regards,
-Xinpeng
