Thank you for your review.  I have written some responses below.

Thanks; fixed in next revision.

I think the motivation is too complicated to concisely summarize in the
abstract.  We could mention that AD-KDC-ISSUED has known shortcomings
that will be detailed in the document, if that helps.

That paragraph indicates that the svc-verifier element of CAMMAC  takes
the same role as the ad-checksum element of AD-KDC-ISSUED.  I think it
doesn't qualify as new in this context.  Please let me know if there is
alternative wording that would make this more clear.

I think of CAMMAC as the abstract concept behind this authorization
data, and of AD-CAMMAC as the ASN.1 type.  If this usage is confusing,
we could change to use AD-CAMMAC more consistently throughout.

"svc" is a common abbreviation for "service", but we can expand it on
the first use if that helps.  KDC is spelled out on its first use in the
Introduction.

RFC 4120 specifies that a server receiving unknown authorization data
MUST fail the authentication process.  Do you think this needs repeating
in this document?
