/**
* Fundamental values that are needed to discern the more specific COSE public key types below.
*
* The use of `Maps` here is due to CBOR encoding being used with public keys, and the CBOR "Map"
* type is being decoded to JavaScript's `Map` type instead of, say, a basic Object as us JS
* developers might prefer.
*
* These types are an unorthodox way of saying "these Maps should involve these discrete lists of
* keys", but it works.
