It’s not an API spec but it does “basically start and end” with the API. It follows the same approach as
draft-ietf-taps-transports-usage, which also very much “basically starts and ends” with the API, in how
primitives are derived. Details on this relationship are maybe clearest in the appendix, where we describe
how to contribute text  (in some future version, this should probably be renamed into “how this document was
created”).

It certainly is the right input for anyone creating an API. E.g., it IS the input from which we derive our protocol-independent
API in the NEAT project.
