YANG is built to address very same requirements as TD. It has updatable properties, rpc`s, event streams, data types etc.

Hi Robert,

Thanks for the input.  Could I kindly ask you for an explanation of what you refer to as interaction types and how these differ from the data models?  In addition, is it possible to point to the use cases and requirements?  This would help the Working Group, as every feature needs to be grounded in commercially relevant use cases.

Many thanks,
