[Brian Sipos <[e-mail]>]

Erik,
This write up is helpful. Thank you!

Under item 8, about validation of "formal language" in the document: there
is CDDL defined in this document, it is checked by CI tools on the document
source, and that CDDL is itself used to validate the example CBOR
diagnostic notation. Mentioning this in case you feel like an update is
useful or if questions come up during later reviews.
