Document: draft-ietf-lamps-rfc5751-bis-07

Summary:
    This document is clearly written and does a nice job of explaining the rationale and historical context of the decisions it made.

Major issues:
    None noticed during this review

Minor issues:
    I was slightly confused by the description of AuthEnvelopedData in 2.4.4: it seems to describe data protected by a symmetric AEAD but then mentions asymmetric keys. But this could be due to my lack of expertise in S/MIME.

Nits/editorial comments: 
    I believe the RFC2119 reference should also mention RFC8174.
