Dear Linda,

Thank you for the review and my apologies for the late reply (I have been moving house).

Replies in-line.

Not typically. The idea is that the TA certificate can be updated w.r.t. its content - contained resources in particular, and Relying Parties can find this certificate at the listed URIs.

Yes, both.

There is another draft currently being in the working group that is concerned with changing TALs - i.e. rolling keys and modifying locations where they may be found:
https://tools.ietf.org/html/draft-ietf-sidrops-signed-tal-02 <https://tools.ietf.org/html/draft-ietf-sidrops-signed-tal-02>

This document (https-tals) is concerned only with allowing HTTPS as an additional scheme for URIs in TALs

> Typo: Section 2.1 second paragraph:  "without needing to effect..", do you mean

"effect" is correct in this context. I think it could be more clearly written as: "without needing to redistribute". If no one objects I am fine with changing this.

Note that this text comes from RFC7730. I tried to keep the changes limited to the addition of HTTPS.


Cheers
Tim
