Overview

Validates a ChangeSet, returning ‘Success(change_set)` if valid, and a `Failure` including the errors otherwise.

Callers provide the particular ‘ChangeSet` to validate, and its validity status is delegated by its own configuration/implementation.

It is good practice to run this validation as a precursor to any step that will sync a ChangeSet or save its resource. A ‘Failure` return value in the context of a transaction will prevent the sync/save step from running.
