Hi EKR,

I have been told that my response [1] to your mail [2] has not reach some of the mailboxes.

Thus on advice of our AD, I am starting a new thread to reach closure on this.

The open point is -
EKR suggested that we use the StartTLS message to indicate the local policy if the PCEP speaker is willing to connect without TLS. Whereas the current document does this by using the error message in case it is unwilling or unable to start the TLS.

EKR proposal works, but will require us to add a new PCEP object - StartTLS object, as unfortunately there is no way to carry the information in the current message/objects format defined.

As an editor, my opinion was to avoid making a change in encoding if possible, especially if the benefit is not big and the default setting is strict TLS.

But if the opinion is towards "mandating" making the change, I can put out a version for review soon.

All the other comments are handled in -16 [3]. Thanks for all the comments and discussions!

Regards,
Dhruv
