Right.

As a reminder, the proposed resolution is as follows:

 * Do not establish a registry now 
      Let the first new header field specification establish it

 * A client that gets an unknown field ignores it 
      This means no mandatory-to-understand extensions

At this stage, a +1 response is OK though not necessary (we got plenty of those in the room), but any disagreement should come with an explanation.

Thanks

Yoav

Please forgive my ignorance, but do LockCA and/or LockEV offer any
functionality that you can't already get with public key pinning as
currently specified?

 Folks, this thread has rather been hijacked.  We need to have some WG input on what registration policy to recommend for a possible future STS header field registry.  That's what this thread is for, and I need to see some WG discussion about it in order that Jeff may finish the document and that I may move it forward.

Please take discussion of LockCA and LockEV to another thread.

Thanks,
Barry
