This document is almost ready to be published as a Proposed Standard,
once the issues noted herein are resolved.
* Forgive me for my limited knowledge of YANG, but is there a reason
key-strings are only representable as either a YANG string or
hex-string type, and not the YANG binary type?
* This document does not provide much guidance around AES key wrap
other than it can be used and the KEK is provided out-of-band/-context.
For instance, AES key-wrapped key-strings probably require using
"hexidecimal-string". Also, assuming I'm reading the model correctly,
it appears this feature applies to the whole chain, which I think is
worth calling out.
* This document warns against using the "clear-text" algorithm, which the
reader is lead to understand is for legacy implementation reasons.
However, is there not a similar concern with cryptographically weak
algorithms, such as md5 and (arguably) sha1?
* In Section 3.2. "Key Chain Model Features", the word "of" is missing
between "configuration" and "an" in the phrase "support configuration an
* I note that idnits is calling out some odd spacing issues, but I think
they are safe to ignore.
