    (Benjamin Kaduk) Discuss

    3) inconsistency / conflicts about the minimum array size of NodeHash

I don't see any issue.  I looked for NodeHash and found three places:

a) 4.9 Merkle Tree Head
	opaque NodeHash<32..2^8-1>
which says the size MUST match the log's HASH_SIZE

b) 4.11 Merkle Consistency Proofs
	NodeHash consistency_path<1..2^16-1>;
This is a vector (array) of NodeHash items, as the text mentions.	

c) 4.12 Merkle Inclusion Proofs
	NodeHash inclusion_path<1..2^16-1>;
This is also a vector (array) as described in the text.

I think Ben is wrong here.

    4) Section 6 on OCSP contains language no longer applicable for the
         latest TLS version 1.3.

    This should be extended to cover 1.3 (or replaced to only cover 1.3
    and no earlier versions??)

https://github.com/google/certificate-transparency-rfcs/pull/320

    5) Need for "greater clarity on the (non-)usage of CT for TLS client 
    certificates"

    Perhaps Benjamin can clarify this request with some more details?
