Taxonomy of Composite Attesters

Abstract

This document was attempting to clarifys and extends the meaning of Composite Attester from RFC9334. It has since been moved into the RATS wiki, and this I-D serves as a tombstone.

A system of annotated diagram components is defined as a small language to explain the different ways that components can interact to form composites.

These diagram components are then used to define a few popular classes of composites.
