TR291 Intent Extension Models v3.6.0

This document describes a proposed set of intent extension models. These extensions address various concerns and purposes, such as validity management of intent and expectation, etc. For these concerns the specified intent extension models add optional additional vocabulary and define its semantics. These models constitute specializations of and extensions of the intent common model presented in IG1253A. They add to a modular landscape of intent models and allow expanding of the model supported by each distinct intent manager. Intent management functions can optionally implement support for intent extension models and announce their support through the intent manager capability profile as described in IG1253D.
