Hi, I have also looked at this document, and there are things that I have think are unclear:
Q1: It is Informational, and it does not update RFC 4960. Instead, it just seems to list the erratas (but without even referencing them, as noted by Paul). I think that it should be made very clear that this document is only for guidance, and that implementers shall use the actual erratas for the actual updates. Q2: Unless I’ve missed it, there is no indication whether the draft only includes the Verified erratas, or also others - in which case the modified text in one or more erratas may still be changed (erratas may even be rejected). Q3: While the draft name contains “-errata-“, it is unclear whether the draft only covers issues for which erratas has been filed, or whether other issues (e.g., issues that have been discussed on the list) are also included. Q4: When looking at the changes, at least in one case I can’t find an associated errata. For example, section 3.34 is associated with Section 10.1. I only find one errata (#5003) associated with Section 10.1, but the changes in that errata does not match what is in the draft. A reference to the actual errata would help. Q5: The text says that the draft includes issues found since publication. Now, there may be more issues after this draft has been published, so it should say something like “at the time of publishing this document”.
