Summary:

This draft is on the right track but has open issues, described in the 
review.

Issues:

Major: 0
Minor: 1
Nits:  2

1) MINOR: In Section 4.1 (Extension Format):

The following:

"CAs SHOULD use the one-way hash function that is associated with the 
certificate signature to compute the hash value, and CAs MAY include 
other hash values."

introduces the possibility that a client might not support *any* of the 
provided hash algorithms. This seems bad.

RFC3709 didn't have this problem because it required that an SHA-1 hash 
be included and supported.

This can be fixed by changing "CAs SHOULD" to "CAs MUST".

2) NIT: From IdNits:

** Downref: Normative reference to an Informational RFC: RFC 1952

I think it would be ok to change the reference to Informative.

3) NIT: Typos

In Section 3 (Logotype Data):

s/then each image objects/then each image object/

In Section 7 (Image Formats):

s/The following table lists many commons/The following table lists many 
common/

s/requirements these image formats/requirements for these image formats/

s/the client will receive response/the client will receive a response/

(The last one above appears twice.)

In Section 10 (Privacy Considerations):

s/cache logotype data is cached/cache logotype data/
