Model for distributed authorization policy sharing

This document defines mechanisms and conventions for the representation, lifecycle management, and distribution of authorization policies in distributed and automated environments. It specifies a consistent, machine-readable, and interoperable framework that enables policies to be validated, versioned, exchanged, and removed across heterogeneous systems and domains. The framework defines how authorization policies, expressed in declarative Policy-as-Code (PaC) languages, are encapsulated, managed, and distributed using YANG as the canonical representation format. This separation allows independent evolution of policy languages, enforcement architectures, and trust models.
